Manufacturing Quality Control of 3-AMINO-4-BROMOPHENOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 280 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., brominated by-products, aniline derivatives) via gradient HPLC with UV detection and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, toluene) using gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine consumption in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (Pb, Cd, Hg, As, etc.) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled combustion at 550-600 C and weighing of the cooled residue. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against established visual standards. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a 1% w/v suspension in purified water using a calibrated pH electrode. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile matter after ignition at 700-750 C, following drying and cooling to constant weight. |
| Bulk Density | Tap Density Tester | Determines mass per unit volume of freely settled and tapped powder using standardized cylinder and tapping mechanism per USP <616>. |
