Manufacturing Quality Control of 3-HYDROXY-5-NITROBENZOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities (e.g., 5-nitrobenzoic acid, 3-hydroxybenzoic acid, dinitro isomers) using gradient HPLC-UV against qualified reference standards. |
| Loss on Drying (LOD) | Gravimetric Thermogravimetry | Measurement of mass loss after drying under controlled temperature (105 °C) and vacuum or nitrogen purge, reflecting volatile solvents and moisture content. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Sulfated Ashing | Determination of inorganic residue after charring organic matter and subsequent ignition with sulfuric acid treatment at 700–800 °C. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) following microwave-assisted acid digestion and plasma emission spectroscopy. |
| Chloride Content | Potentiometric Titration with AgNO₃ | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential jump due to AgCl precipitation. |
| pH of Aqueous Suspension | pH Potentiometry | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode, indicating acidic character from carboxylic group dissociation. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection via visual observation of solid-to-liquid phase change in a capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical form (crystalline powder), color (off-white to pale yellow), and absence of visible foreign particles under standardized lighting and conditions. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical quantification of water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers (if present as enantiomerically enriched material) in solution at specified concentration and wavelength (e.g., 589 nm). |
