| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as a nucleotide-based drug intermediate for synthesizing antiviral agents (e.g., cytarabine derivatives) and nucleic acid therapeutics | Prepared via enzymatic or chemical phosphorylation under sterile conditions, followed by purification, crystallization, and lyophilization to obtain high-purity active pharmaceutical ingredient (API) |
| Biotechnology | Added to cell culture media to support cell proliferation and differentiation, particularly in stem cell and immune cell cultures | Supplemented into serum-free or low-serum media at typical concentrations of 1–10 μM; requires light-protected storage at 2–8 °C to maintain stability |
| Diagnostics | Employed as a cofactor substrate for reverse transcriptase in real-time quantitative PCR (qPCR) and digital PCR (dPCR), enhancing cDNA synthesis efficiency and fidelity | Co-formulated with dNTPs in the reverse transcription reaction system at defined molar ratios (e.g., CTP:ATP:GTP:UTP = 1:1:1:1), typically at a final concentration of 0.5 mM |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on retention time and UV absorbance at 280 nm relative to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of structurally similar impurities using gradient reversed-phase chromatography. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in anhydrous methanol-based medium. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash residue after controlled high-temperature incineration at 500-600 C. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Ni by atomic emission spectroscopy after acid digestion. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Determination using calibrated glass electrode in a standardized aqueous solution at 25 C. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral cytidine moiety in solution. |
| Organic Volatile Impurities | GC-FID | Identification and quantification of residual solvents using capillary gas chromatography with flame ionization detection. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and detection of specified pathogens per pharmacopeial procedures. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder particle size via scattering pattern of laser beam through dispersed sample. |
| Sodium Content | Flame Photometry | Quantification of Na+ ions based on characteristic emission intensity at 589 nm in flame excitation. |
| Sterility | Direct Inoculation | Confirmation of absence of viable microorganisms by incubation in fluid thioglycollate and soybean-casein digest media. |
