Manufacturing Quality Control of 4-Methoxy-2-nitrobenzoic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, physical state, and presence of visible impurities under natural or standard lighting conditions. |
| Melting Point | Capillary Melting Point Method | Determine the melting temperature range using a melting point apparatus, compare with standard values (literature value approximately 148–150 °C) to assess purity. |
| Content (Purity) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column and a UV detector (e.g., 254 nm) to quantify the main component based on retention time and peak area. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Same as above; detect possible synthetic intermediates, by-products, or degradation products using gradient elution and assess total impurity levels. |
| Moisture | Karl Fischer Titration | Determine moisture content using Karl Fischer reagent; suitable for trace moisture analysis to ensure the product meets drying requirements. |
| Residual Solvents | Gas Chromatography (GC) | Analyze possible residual organic solvents (e.g., methanol, ethyl acetate) from the manufacturing process using headspace or direct injection methods. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Digest the sample and measure the content of heavy metals such as lead, cadmium, mercury, and arsenic to meet pharmacopoeia or safety standards. |
| Residue on Ignition | Gravimetric Method | Ignite the sample at high temperature until constant weight, then weigh the residue to evaluate the level of inorganic impurities. |
| pH Value (Solution) | pH Meter Method | Measure the acidity or alkalinity of a water suspension or solution of the sample using a pH meter; applicable for water solubility evaluation. |
| Infrared Spectrum (IR) | Fourier Transform Infrared Spectroscopy (FT-IR) | Obtain an IR spectrum using the KBr pellet method and compare with reference spectra to confirm chemical structure consistency. |
