Manufacturing Quality Control of 4,6-DIAMINO-2-MERCAPTOPYRIMIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Separates and quantifies impurities using gradient HPLC-UV; individual impurities are calculated relative to main peak area. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration using iodine generated in situ via reaction with water in methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and weighing of the cooled crucible. |
| Heavy Metals | ICP-OES | Quantifies total heavy metals (e.g., Pb, Cd, Hg, As) after acid digestion by optical emission spectroscopy at element-specific wavelengths. |
| Sulfur Content | Oxidative Combustion followed by Ion Chromatography | Converts organic sulfur to sulfate via high-temperature combustion; sulfate is separated and quantified by IC conductivity detection. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions after sample dissolution and filtration; detected via suppressed conductivity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% w/v aqueous suspension using calibrated glass electrode and pH meter. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation of phase change. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against standard white background under controlled lighting. |
| Bulk Density | Graduated Cylinder Method | Calculates mass per unit volume by measuring weight of material freely poured into a calibrated cylinder. |
| Organic Volatile Impurities | GC-FID | Identifies and quantifies residual solvents using gas chromatography with flame ionization detection and external calibration. |
