Manufacturing Quality Control of 3-Hydroxy-4-nitrobenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection; impurities quantified relative to main peak using response factors. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common organic solvents (e.g., methanol, acetone, ethyl acetate) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent; water reacts stoichiometrically with iodine in pyridine/methanol medium. |
| Heavy Metals | ICP-MS | Multi-element trace metal analysis after acid digestion; detection based on mass-to-charge ratio of metal ions in plasma ionization source. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anions on anion-exchange column with suppressed conductivity detection; quantification via calibration curve. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by sulfuric acid treatment and final weighing of non-volatile residue. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of crystalline solid against established reference standard under controlled lighting. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volume-based particle size distribution in dispersed slurry. |
| Loss on Drying | Thermogravimetric Analysis | Weight loss measured after heating sample at 105 C for 2 hours; reflects volatile content including residual moisture and solvents. |
