Manufacturing Quality Control of 4-BROMO-3-NITROBENZONITRILE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Separates and quantifies impurities (e.g., isomers, residual starting materials) via gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., DMF, toluene) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures trace water by coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Heavy Metals | ICP-OES | Determines total heavy metal content (Pb, Cd, Ni, etc.) after acid digestion by measuring atomic emission intensities. |
| 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 combustion of sample with sulfuric acid pretreatment. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting against standard references. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension using angular scattering pattern of laser light. |
| Bulk Density | ASTM D1895 | Determines mass per unit volume of freely settled powder using standardized cylinder and tapping procedure. |
| Loss on Drying | Thermogravimetric Analysis | Measures weight loss upon heating to remove volatiles (e.g., moisture, residual solvents) under controlled conditions. |
