Manufacturing Quality Control of 87-39-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies purine derivative concentration via absorbance at characteristic wavelength (e.g., ~260 nm) using molar absorptivity. |
| Moisture Content | Karl Fischer Titration | Determines water content by coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities as ash mass after high-temperature incineration. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomic absorption of light at element-specific wavelengths after acid digestion. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions via precipitation titration monitored by silver ion-selective electrode. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Determines sulfate as insoluble BaSO4 precipitate, isolated and weighed after digestion and filtration. |
| Iron Impurity | Colorimetric Spectrophotometry (1,10-Phenanthroline) | Forms orange-red Fe(II)-phenanthroline complex; absorbance measured at ~510 nm for quantification. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measures hydrogen ion activity in saturated aqueous suspension using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid under controlled heating. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents or volatile organics using flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in intensity of laser light scattered by dispersed particles. |
| Bulk Density | Graduated Cylinder Method (ASTM D1895) | Determines mass per unit volume of freely settled powder in standardized cylinder under defined conditions. |
