Shop China Supply Nucleotides Cytosine Powder with Factory Price-Detailed Image 2

Product Name: 2'-Fluoro-2'-deoxyadenosine
CAS Number: 64183-27-3
Molecular Formula: C₁₀H₁₂FN₅O₃
Molecular Weight: 269.23 g/mol
Appearance: White to off-white crystalline powder.

2'-Fluoro-2'-deoxyadenosine (CAS 64183-27-3) is a high-purity, fluorinated purine nucleoside analog featuring a fluorine atom at the 2'-position of the deoxyribose moiety. This strategic fluorination significantly enhances the compound's metabolic stability, lipophilicity, and resistance to enzymatic degradation compared to its non-fluorinated counterparts, making it a valuable scaffold in medicinal chemistry and drug development programs. The compound is extensively employed as a key intermediate in the synthesis of potent antiviral agents (including hepatitis C and HIV inhibitors) and anticancer therapeutics targeting DNA polymerases and ribonucleotide reductases. Its unique structural properties also render it useful in positron emission tomography (PET) imaging probe development and mechanistic studies of nucleic acid metabolism. Supplied as a white to off-white crystalline powder with excellent purity profiles, this compound demonstrates good solubility in aqueous and organic media, facilitating seamless integration into multi-step synthetic routes, nucleoside phosphorylation protocols, and structure-activity relationship (SAR) studies. It is suitable for both early-stage research and GMP-compliant scale-up manufacturing, delivering consistent quality and reproducible performance across diverse applications in pharmaceutical and biochemical research.

Conclusion	It complies to the standard

For regulatory compliance (e.g., USP, EP, JP), raw material Vidarabine must meet several rigorous standards:

Assay (by HPLC): 98.0% – 102.0% on an anhydrous basis.
Related Substances: Limits for specific impurities, notably Ara-Hx (NMT 2.0%), as well as any unspecified individual impurity (NMT 0.1%) and total impurities (NMT 2.0%).
Residual Solvents: Must comply with ICH Q3C guidelines (Class 1 and 2 solvents limited or absent).
Heavy Metals: NMT 20 ppm (typically lower for injectable grades).
Water Content (Karl Fischer): NMT 6.0% (the material is hygroscopic to a degree).
Microbial Limits: Total aerobic microbial count (TAMC) ≤ 1000 CFU/g, absence of S. aureus, P. aeruginosa, and Candida albicans.

As a high-purity pharmaceutical intermediate, L-Tyrosine Ethyl Ester Hydrochloride is predominantly utilized in the chemical synthesis of bioactive peptides, dopamine analogs, and melanin precursors. Its excellent solubility profile makes it an ideal chiral building block for asymmetric synthesis and a critical substrate in enzymatic reactions. Available in purity grades of ≥98% (HPLC), it meets stringent requirements for R&D and cGMP manufacturing processes. Reliable supply ensures batch-to-batch consistency for long-term project scalability.

Vidarabine is classified as a potential reproductive hazard and an irritant. Safety Data Sheets (SDS) mandate the following:

Hazard Statements (H360): May damage fertility or the unborn child (Category 1B).
Precautionary Measures: Use fume hoods and wear impermeable gloves (e.g., nitrile), lab coats, and safety goggles. Avoid generating airborne dust.
First Aid: In case of skin contact, wash immediately with copious soap and water. If inhaled, move to fresh air.
Storage: Store in tightly sealed, light-resistant containers at 2°C to 8°C (refrigerated) for long-term stability. Avoid freezing.

While superseded by newer nucleoside analogs (Acyclovir, Ganciclovir) for systemic use due to better bioavailability and lower toxicity, Vidarabine retains niche value. Its primary current application is ophthalmic ointment (3%) . Pharmacokinetically, the raw material has poor oral bioavailability (<10%) and is rapidly deaminated in the gastrointestinal tract, necessitating parenteral or topical administration.

Vidarabine API is a well-characterized, stable crystalline nucleoside analog. While its systemic use has declined, it remains a critical raw material for topical antiviral ophthalmic preparations, particularly where resistance to other agents occurs. Manufacturers must strictly control impurities (especially Ara-Hx) and water content to ensure final drug product efficacy.
