Manufacturing Quality Control of 2-Chloro-4-hydroxybenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, ethyl acetate) based on calibrated external standards. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppq sensitivity. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by abrupt potential change due to AgCl precipitation. |
| Moisture Content | Karl Fischer Coulometric Titration | Electrochemical generation of titrant (iodine) proportional to water content; precise measurement based on Faraday's law. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary method per USP <741>. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a saturated aqueous suspension (1:10 w/v) using a calibrated glass electrode pH meter. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by sulfuric acid treatment and final weighing of residual inorganic ash. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion via laser scattering; size distribution calculated from angular intensity pattern using Mie theory. |
| Organic Volatile Impurities (OVI) | GC-MS | Screening and semi-quantitative identification of non-specified volatile organics using gas chromatography coupled with mass spectrometry. |
| Residue on Ignition | Gravimetric Analysis | Weight loss upon high-temperature ignition (600-750 C) to determine non-volatile inorganic residue content. |
