Product Detail ——

Nicotinamide Adenine Dinucleotide, abbreviated as NAD, is a vital nucleotide coenzyme biochemical raw material widely applied in modern life science laboratory research. Our company adopts mature and stable full organic total synthesis production route, abandoning the traditional biological extraction process, which can effectively control batch difference, impurity content and product stability of finished goods. Every production step is equipped with standardized process monitoring links, from raw material feeding, multi-step cyclic synthesis, intermediate separation and purification to final recrystallization refinement, each node is inspected and recorded by professional quality testing personnel to guarantee consistent product quality among different batches.

The finished NAD product we supply is uniform white crystalline powder, with no visible caking, discoloration or foreign impurities under visual observation. We strictly control the HPLC purity of all finished products to 99%, regularly test related indicators including moisture content, heavy metal residue, insoluble particulate matter and residual organic solvent, and each batch can be accompanied by a complete official Certificate of Analysis document, which covers all test item data, chromatogram spectrum and quality judgment standard, fully meeting the document filing requirements of universities, biological research laboratories, pharmaceutical research and development institutions and other academic units, and also conforms to cross-border commodity import inspection standards of various countries and regions around the world.

Key Product Characteristics & Performance Advantages Excellent chemical stability: The molecular structure of NAD crystalline powder is stable under sealed and light-proof environment. Vacuum aluminum foil sealed packaging can effectively isolate air, moisture and ultraviolet light erosion during transportation and storage, avoiding hydrolysis, oxidation and deterioration of active components. Conventional room temperature cross-border transportation will not cause quality attenuation of the product; when stored under specified low temperature conditions, the effective shelf life can be up to 24 months. High solubility in aqueous system: The product can be rapidly and fully dissolved in sterile purified water, PBS buffer solution, cell culture medium and various conventional laboratory aqueous reagent systems, without insoluble precipitate remaining after dissolution. Researchers can freely prepare working solutions with different concentration gradients according to specific experimental schemes, and the prepared liquid solution maintains stable properties within the validity period, which will not affect the accuracy and repeatability of subsequent cell experiments and biochemical detection results. Low impurity interference: Strict multi-stage chromatographic purification technology removes intermediate by-products, residual raw materials and miscellaneous ions generated in the synthesis process, the content of all irrelevant impurities is controlled at an extremely low level, which effectively avoids extra interference variables in redox reaction research, intracellular energy metabolism exploration, gene pathway regulation experiments and other academic projects, greatly reducing experimental error probability. Diversified customizable packaging: We design multiple packaging specifications to adapt to different usage demands of customers. Small trial specifications include 100mg, 500mg, 1g vacuum aluminum foil bags, suitable for preliminary exploratory small-scale experiments; medium batch specifications adopt 5g, 10g sealed packaging; large-scale bulk wholesale goods are packed in 25kg food-grade cardboard drums with built-in double-layer plastic lining bags, which can meet the long-term continuous experimental consumption demand of large research institutions and raw material formula development enterprises.

Defined Application Scope (Strict Compliance Statement) We clearly stipulate that this high-purity NAD raw material is only allowed to be used for in-vitro laboratory academic scientific research activities, the applicable research directions include intracellular energy metabolism mechanism research, cellular redox balance exploratory test, biological metabolic pathway analysis, enzyme activity detection experiment, molecular biology related reagent formula development and other life science basic research projects.

This product has not passed the drug approval, food safety evaluation and health care product filing procedures of any national regulatory authority. It is strictly forbidden for buyers to use this product for human oral ingestion, clinical disease auxiliary treatment, dietary supplement raw material blending, oral capsule and tablet production, as well as cosmetic raw material addition and daily chemical product processing. Any off-standard usage beyond the scope of laboratory scientific research shall be fully undertaken by the purchaser, our company will not bear any legal risk and consequence arising from improper application.

Standard Storage Operation Specifications Short-term temporary storage (within 3 months): Tighten the packaging seal completely, place the product in a dry and cool environment away from direct sunlight, and store it in a refrigerator at 2°C to 8°C; do not open the packaging repeatedly to prevent moisture and air from entering the container. Long-term sealed preservation (more than 3 months): Put a desiccant together with the product inside the packaging bag, exhaust excess air and seal tightly, store at a constant low temperature of -20°C, strictly avoid repeated freezing and thawing cycles, otherwise the crystalline structure will be damaged and product stability will decline. Preservation after dissolution: After the powder is dissolved into aqueous experimental solution, it is recommended to finish all usage within 7 days under 2°C~8°C refrigeration; the residual unused liquid cannot be stored for a long time and needs to be discarded properly to prevent microbial contamination and component degradation.
