Manufacturing Quality Control of 958-09-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies 2'-deoxyadenosine by separation on a reversed-phase column and UV detection at 260 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., adenine, adenosine, deoxyguanosine) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetonitrile, ethyl acetate) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based reagent stoichiometry. |
| Heavy Metals | ICP-MS | Quantifies trace heavy metals (Pb, Cd, Hg, As, etc.) by inductively coupled plasma mass spectrometry after acid digestion. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature incineration followed by weighing of the non-volatile residue. |
| Optical Rotation | Polarimetry | Measures specific optical rotation using sodium D-line light to confirm chiral integrity and identity. |
| pH (1% w/v solution) | Potentiometric pH Measurement | Determines acidity/basicity of aqueous solution using calibrated glass electrode and pH meter. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic mesophilic microorganisms and detects absence of specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial procedures. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution by measuring angular scattering pattern of laser light. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, confirming identity and purity. |
| Chloride Content | Ion Chromatography | Quantifies chloride ion impurity using suppressed conductivity detection after anion exchange separation. |
