Manufacturing Quality Control of 4-cyano-3-methylbenzoic 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 common solvents (e.g., methanol, toluene, DMF) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element detection after acid digestion; total heavy metals (Pb, Cd, Hg, As) reported as mg/kg against USP <231> limits. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection with sodium carbonate eluent. |
| Sulfate Impurity | Ion Chromatography | Quantification of sulfate ions by ion chromatography with conductivity detection following sample dissolution in water. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated digital apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against established reference standard. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (700-800 C) to determine inorganic ash content. |
| Bulk Density | Tap Density Tester | Measurement of mass per unit volume after standardized tapping per USP <616> to assess powder flow characteristics. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution in suspension using Mie scattering theory and validated instrument calibration. |
