Manufacturing Quality Control of 2-Methoxy-4-nitrobenzoic 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, ethyl acetate) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, As, Hg, and others after acid digestion, using plasma emission spectroscopy calibrated with matrix-matched standards. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions after aqueous extraction and filtration; quantified via calibration curve. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by sulfuric acid treatment and final weighing of residual inorganic ash. |
| 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 samples. |
| Particle Size Distribution | Laser Diffraction | Measurement of size distribution in dispersed dry powder using Mie scattering theory and validated optical model. |
| Acid Value | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized NaOH solution using phenolphthalein indicator or potentiometric endpoint detection. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity (though compound is achiral, used for consistency verification). |
