Manufacturing Quality Control of Methyl 4-aminobenzoate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities by reversed-phase HPLC with UV detection, relative to the main peak using area normalization or external standard method. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents using gas chromatography with flame ionization detection and internal standard calibration. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Multi-element quantitative analysis after acid digestion, based on atomic emission intensity at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Determination of inorganic residue mass after controlled incineration at 700-800 C followed by weighing. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement via visual observation of solid-to-liquid phase change in a capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of the sample against standard references under controlled lighting conditions. |
| pH of Aqueous Solution | pH Meter | Electrochemical measurement of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity or absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to determine volume-based particle size distribution in a dispersed dry or wet sample. |
