Manufacturing Quality Control of 4-HYDROXY-3-METHOXY-5-NITROBENZOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Loss on Drying | Gravimetric Method | Measurement of mass loss after drying under controlled temperature and vacuum, reflecting volatile content and residual solvents. |
| Residue on Ignition | Sulfated Ash Method | Determination of inorganic residue after high-temperature combustion of sample with sulfuric acid pretreatment. |
| Heavy Metals | AAS (Flame or Graphite Furnace) | Quantification of Pb, Cd, Hg, As, and other regulated metals by atomic absorption spectroscopy after acid digestion. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Sulfate Content | Gravimetric Method | Precipitation as barium sulfate followed by filtration, drying, and weighing of the precipitate. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a saturated aqueous suspension using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range at which solid-to-liquid phase change occurs, per USP <741>. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on iodine consumption in a reaction specific to water in anhydrous methanol/pyridine medium. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to derive volume-based particle size distribution in dispersed dry or wet samples. |
| Organic Volatile Impurities (Residual Solvents) | GC-FID | Separation and quantification of specified solvents (e.g., methanol, acetone, ethyl acetate) using gas chromatography with flame ionization detection. |
