Product Description
Cytidine (CAS 65-46-3), also known as Cytosine β-D-riboside ， is a pyrimidine nucleoside formed by cytosine combined with D-ribose via a β-N1-glycosidic bond. As a naturally occurring nucleoside, it is an important component of RNA and a precursor for uridine biosynthesis. It appears as a white to off-white crystalline powder, odorless and slightly bitter in taste, easily soluble in water, and widely used in pharmaceutical, biochemical research and biotechnology fields, mainly as an intermediate for anti-tumor and anti-viral drugs and a biochemical reagent.
1. Physical Properties
White to off-white crystalline powder, odorless, slightly bitter in taste; easily soluble in water, soluble in DMSO, slightly soluble in ethanol; density about 1.4 g/cm3; melting point 210–220 °C (decomposes); stable in low temperature and dry environment.
2. Chemical Properties
A pyrimidine nucleoside formed by cytosine and D-ribose via β-N1 glycosidic bond; exhibits weak acidity and alkalinity; stable in neutral and weakly acidic solutions; easily oxidized under strong oxidizing conditions; sensitive to moisture and light, and may degrade upon prolonged exposure.
3. Storage & Safety Properties
Storage: Store in a sealed container at 2–8 °C, keep dry and light-proof, avoid contact with moisture and strong oxidants to prevent degradation. Safety: Low toxicity, non-irritating; avoid inhalation, ingestion or contact with eyes; no flammable or explosive hazards. Transportation: Comply with relevant regulations, use sealed packaging to prevent moisture absorption and contamination, and can be transported by conventional means.
