Manufacturing Quality Control of 4-BROMO-3-HYDROXYBENZOIC 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. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., methanol, ethyl acetate) against calibrated standards. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using isotopic detection for high sensitivity and specificity. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified via calibration curve. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-750 C followed by weighing of residual inorganic salts after sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range where solid transforms to liquid. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light and specified viewing conditions. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity vs. angle to determine volume-based particle size distribution in dispersed phase. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after ignition at 600 C in a platinum crucible. |
