Manufacturing Quality Control of 3-Hydroxy-2-nitrobenzoic 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 threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, ethyl acetate) against calibrated standards. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction with water. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against sodium chloride 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 | Determination of temperature range over which solid transitions to liquid, using calibrated digital apparatus per USP <741>. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated electrode and temperature compensation. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to determine volume-based particle size distribution from light scattering patterns. |
| Organic Volatile Impurities (OVI) | GC-MS | Targeted and untargeted screening of residual process-related organics using mass spectral identification and semi-quantitative analysis. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light at 20 C using sodium D-line (589 nm) to assess chiral purity and identity confirmation. |
