Description

Cytidine CAS NO 65-46-3 is a fundamental pyrimidine nucleoside, consisting of cytosine linked to a ribose sugar via a β-N1-glycosidic bond. This compound is a critical building block for nucleic acid synthesis and serves as a key intermediate in cellular metabolism. It is essential for research and production in the pharmaceutical, biotechnology, and nutraceutical industries, where it is used in the synthesis of oligonucleotides, antiviral drugs, and as a cell culture supplement.

Application

• Pharmaceutical Intermediate: Key raw material in the synthesis of antiviral and anticancer nucleoside analogs.
• Biochemical Research: Essential substrate and standard in enzymatic studies, metabolic pathway analysis, and molecular biology.
• Cell Culture & Media Supplement: Used as a nutrient component in cell culture media to support the growth of various cell lines.
• Oligonucleotide Synthesis: Serves as a protected monomer (e.g., as N-acetylcytidine) for solid-phase synthesis of DNA and RNA sequences.
• Nutraceutical Ingredient: Investigated for use in dietary supplements targeting cognitive and neurological health.
• Diagnostic Reagent Manufacturing: Utilized in the production of kits and reagents for clinical diagnostics and genetic testing.

Quality Control

Our Cytidine is manufactured under strict quality management systems. It is available in various purity grades, including high-purity standards suitable for pharmaceutical research and production. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We can supply material compliant with in-house specifications, and customization to meet specific pharmacopeial standards (e.g., USP, EP) is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light to maintain stability and purity.
