Manufacturing Quality Control of METHYL 4-BROMO-2-NITROBENZOATE
| 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 via retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, dichloromethane) 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 (as Pb) | ICP-OES | Multi-element detection after acid digestion; quantification by emission intensity at characteristic wavelengths using internal standard calibration. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; quantified using chloride standard calibration. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by weighing of residual inorganic ash after treatment with sulfuric acid. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, observed visually under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of sample against defined standards under controlled lighting conditions. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution of known concentration and path length. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue after ignition at 600-650 C to determine non-volatile inorganic contaminants. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination using calibrated glass electrode in a saturated aqueous suspension or dilute solution. |
