Manufacturing Quality Control of 4-Bromo-2-nitroaniline
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., isomers, nitro-reduction by-products) via gradient HPLC separation and UV response relative to main peak. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., methanol, toluene) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration with iodine-based reagent, based on stoichiometric reaction with water. |
| Heavy Metals | ICP-OES | Measures total heavy metal content (Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after high-temperature incineration of sample with sulfuric acid, expressed as weight percent. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via thermal behavior. |
| Loss on Drying | Thermogravimetric Analysis | Measures mass loss upon heating under controlled conditions, reflecting volatile matter and residual solvents. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water), indicating acidic/basic impurities. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension using angular scattering pattern of laser light. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral compounds; used to confirm absence of racemization or chiral impurities. |
