Manufacturing Quality Control of 5-BROMOISOPHTHALIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities by HPLC separation and UV response relative to main peak. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents using gas chromatography with flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Heavy Metals | ICP-OES | Determines total heavy metal content (e.g., Pb, Cd, Ni) by atomic emission spectroscopy after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Loss on Drying | Gravimetric Method | Measures weight loss after drying under controlled temperature and vacuum, reflecting volatile content. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated electrode. |
| Residue on Ignition | Gravimetric Ashing | Quantifies inorganic residue after high-temperature combustion of sample in a platinum crucible. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of dry powder using angular scattering pattern of laser light. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral molecules in solution, indicating enantiomeric integrity. |
