Manufacturing Quality Control of 3-Fluoro-4-hydroxybenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., starting materials, intermediates, isomers) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, ethyl acetate). |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion and matrix-matched calibration. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions following aqueous extraction and filtration. |
| Sulfated Ash | Gravimetric Analysis | Ignition at 700-800 C followed by weighing of residual inorganic ash after sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature range using calibrated capillary apparatus per USP <741>. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a 1% w/v suspension in purified water using a calibrated electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder via laser scattering to determine D10, D50, D90 values according to ISO 13320. |
| Loss on Drying | Thermogravimetric Analysis | Weight loss measured after drying at 105 C for 2 hours under forced-air conditions. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light (589 nm) in solution per USP <781>. |
