Manufacturing Quality Control of BROMOMALEIC ANHYDRIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV absorbance at 210-230 nm. |
| Moisture Content | Karl Fischer titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acid Value | Acid-base titration with NaOH | Neutralization of acidic groups (e.g., anhydride, carboxylic acid) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric analysis | Determination of non-volatile inorganic impurities by high-temperature ashing followed by weighing of the residual ash. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of trace metals after acid digestion, based on element-specific atomic emission intensities. |
| Chloride Impurity | Ion chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Bromine Content | Oxidative combustion followed by potentiometric titration | Total bromine converted to bromide, then titrated with silver nitrate using a silver indicator electrode. |
| Melting Point | Capillary melting point apparatus | Thermal transition observed as the temperature range over which solid phase converts to liquid under controlled heating. |
| Appearance | Visual inspection | Assessment of physical state, color, and presence of foreign particles under standardized lighting and viewing conditions. |
| Solubility in Common Solvents | Qualitative dissolution test | Observation of complete dissolution in specified solvents (e.g., acetone, chloroform) at room temperature. |
| Volatile Impurities | Gas chromatography (GC-FID) | Separation and detection of low-boiling organic impurities using flame ionization detection after headspace or direct injection. |
| Residual Solvents (e.g., acetone, toluene) | Headspace GC-FID | Quantification of volatile organic solvents via equilibrium partitioning into headspace gas followed by GC separation and FID detection. |
