Manufacturing Quality Control of 4-Amino-2-methylbenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography. |
| Related Substances | HPLC with UV detection | Separation and quantification of structurally related impurities (e.g., isomers, deaminated or oxidized by-products) using gradient elution and UV absorbance. |
| Residual Solvents | GC-FID or GC-MS | Headspace gas chromatographic separation followed by flame ionization detection or mass spectrometric identification/quantification per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS or AAS | Quantification of toxic elements (e.g., Pb, Cd, Hg, As) after acid digestion, based on atomic emission or absorption signals. |
| Loss on Drying (LOD) | Gravimetric thermogravimetry | Mass loss measured after drying at 105 °C under controlled conditions, reflecting volatile content including residual solvents and moisture. |
| Melting Point | Capillary melting point apparatus | Thermal transition temperature range determined by observing solid-to-liquid phase change under standardized heating rate. |
| Chloride Content | Ion Chromatography (IC) or potentiometric titration | Quantification of chloride ions via anion exchange separation with conductivity detection or argentometric titration using AgNO₃. |
| pH of Aqueous Suspension | pH meter measurement | pH value measured in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode to assess acidic/basic impurities. |
| Appearance and Color | Visual inspection and APHA color scale | Subjective assessment of physical state (crystalline powder) and color intensity compared to platinum-cobalt standards. |
| Residue on Ignition | Gravimetric sulfate ash test | Non-volatile inorganic residue quantified after high-temperature (700–800 °C) ignition of sample. |
| Water Content | Karl Fischer titration | Volumetric or coulometric determination of water based on stoichiometric reaction with iodine in pyridine/methanol medium. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers; confirms absence of racemization or chiral impurities. |
| Particle Size Distribution | Laser diffraction | Analysis of scattered laser light intensity patterns to determine volumetric particle size distribution in dispersed powder samples. |
| Microbial Limits | Membrane filtration and colony counting | Quantification of aerobic microorganisms and absence of specified pathogens (e.g., E. coli, S. aureus) per pharmacopoeial methods (USP <61>). |
