Selank is a synthetic peptide derivative supplied by Guangzhou Boyuan Outdoor Products Co., Ltd. exclusively as a non‑hazardous, laboratory‑grade biochemical reagent for qualified research institutions and commercial laboratories. The product is strictly intended for in‑vitro experiments, analytical studies, and peptide‑based biochemical research. It has no claims or applications related to human or veterinary medicine, therapy, diagnosis, or any form of in‑vivo administration. Selank is produced and handled as a general chemical reagent, not as a drug, active pharmaceutical ingredient, medical device, or hazardous material. This product introduction describes the intended use, physical formats, specifications, ordering model numbers, handling recommendations, storage conditions, quality documentation, shipping classification, and purchasing qualifications for Selank. The buyer is solely responsible for determining the suitability of the product for their specific research application.

From a chemical identification perspective, Selank is a synthetic peptide with a defined amino acid sequence and a known molecular weight range. The product is manufactured using standard protocols for research‑grade peptide derivatives. Each batch of Selank is accompanied by a CAS registry number to enable unambiguous chemical referencing. The commonly referenced CAS number for Selank is 881414‑89‑5. Different salt forms, counterions, or specific synthetic variants of this peptide derivative may have different CAS numbers. Therefore, the company provides the exact CAS number applicable to each batch on the Certificate of Analysis. Researchers are encouraged to verify the CAS number against the documentation supplied with each shipment to ensure accurate chemical identification for their laboratory records, material safety data sheet retrieval, and any internal chemical inventory systems.

In terms of physical format and appearance, Selank is supplied primarily as a lyophilized (freeze‑dried) powder. The physical appearance of the lyophilized material is a white to off‑white porous solid. This porous structure is characteristic of materials that have undergone a freeze‑drying process under controlled conditions. The material may present as a loose powder that flows freely within the container, or it may form a cohesive cake or plug at the bottom of the vial, depending on the specific lyophilization cycle parameters used during manufacturing. Both presentations are acceptable for a research‑grade lyophilized chemical reagent. For research applications that require a ready‑to‑use format without a reconstitution step, Selank may also be supplied as a clear, colorless to very slightly straw‑colored liquid. The solution format is free from visible particulates, cloudiness, or discoloration. Any significant deviation from these appearance descriptors would trigger a quality investigation, although such deviations are rare under proper manufacturing and storage conditions. The product is not represented as sterile unless explicitly stated and certified on the product label. For applications that require sterile material, the end user must perform appropriate filtration using standard laboratory equipment.

Guangzhou Boyuan Outdoor Products Co., Ltd. supplies Selank in multiple net content quantities to accommodate different laboratory needs and research scales. For the lyophilized powder format, common unit sizes include 5 milligrams per vial, 10 milligrams per vial, and 20 milligrams per vial. Each vial contains the stated net peptide content, and the fill weight is verified through standard analytical methods appropriate for non‑pharmaceutical chemical reagents. For the solution format, common concentrations include 0.1 percent (weight/volume), 0.15 percent, and 0.2 percent (weight/volume). Custom content quantities or custom solution concentrations may be available upon request, subject to minimum order quantities and manufacturing feasibility. The net content or concentration is printed on the product label along with the batch number and expiration date.

To facilitate efficient ordering, inventory management, and customer communication, Guangzhou Boyuan Outdoor Products Co., Ltd. assigns an internal model number to each distinct product specification. These model numbers serve as ordering codes and tracking identifiers. Examples of model numbers for Selank include the following: BY‑SEL‑5MG for the 5 milligram lyophilized powder vial, BY‑SEL‑10MG for the 10 milligram lyophilized powder vial, BY‑SEL‑S01 for the 0.1 percent solution, and BY‑SEL‑S015 for the 0.15 percent solution. These model numbers are purely logistical identifiers. The model numbers are printed on the product label alongside the product name, net content, batch number, storage instructions, and CAS number where applicable. Customers are encouraged to use the model numbers when placing orders to ensure accurate product selection.

The CAS number for Selank is an important element for chemical identification. As noted above, the commonly referenced CAS number for this synthetic peptide derivative is 881414‑89‑5. This CAS number corresponds to a specific chemical structure and salt form. Different salt forms may have different CAS numbers. The company provides the exact CAS number for each batch on the Certificate of Analysis. The CAS number allows researchers to perform accurate chemical database searches and maintain consistent chemical inventory records. The product label includes the CAS number where space permits, and the accompanying documentation always includes the CAS number for the specific batch supplied.

Handling recommendations for Selank are consistent with standard laboratory practices for non‑hazardous chemical reagents. For the lyophilized powder format, the vial should be allowed to reach room temperature before opening. This practice helps prevent moisture condensation on the cold powder surface when the vial is opened. The appropriate volume of a suitable solvent is then added. Suitable solvents include distilled water, phosphate‑buffered saline, or other aqueous buffers commonly used in peptide research. The solvent should be added gently, and the mixture should be swirled carefully without vigorous shaking. Vigorous shaking is not recommended as it may cause physical aggregation or foaming. The powder typically dissolves within a short period, depending on the solvent and temperature. Once dissolved, the solution should be used according to the researcher's experimental design. For the solution format, the product is ready to use as supplied. No reconstitution step is required. The solution should be handled using standard laboratory techniques, including the use of clean pipettes or syringes to withdraw the required volume.

Storage conditions for Selank are specified to maintain the chemical stability of the product over its labeled shelf life. The lyophilized powder should be stored at temperatures between 2 degrees Celsius and 8 degrees Celsius. The storage environment must be dry and protected from direct light exposure. Under these recommended conditions, the lyophilized product remains stable for a period of 12 to 24 months from the date of manufacture, depending on the specific batch and storage practices. The solution format has a shorter recommended storage period, typically 3 to 6 months under the same temperature and light protection conditions, unless otherwise stated on the product label. Once the lyophilized powder has been reconstituted into a solution, the reconstituted material should be used promptly or divided into aliquots and stored frozen, typically at minus 20 degrees Celsius or minus 80 degrees Celsius, to minimize repeated temperature cycling. Freeze‑thaw cycles should be limited because repeated freezing and thawing may affect the physical consistency of the solution.

Quality documentation for Selank includes a Certificate of Analysis that is available upon request. The Certificate of Analysis typically includes the following information: product name, model number, batch number, date of manufacture, net content or concentration, physical appearance description, CAS number, and purity assessment data where applicable. Purity assessment is performed using high‑performance liquid chromatography as a standard analytical method for peptide derivatives. Mass spectrometry may be used for molecular weight confirmation. The Certificate of Analysis is provided as a courtesy to assist researchers in their own quality assessment. The buyer remains responsible for any additional testing or validation required for their specific research application.
