Manufacturing Quality Control of 4-BROMO-3-CHLOROPHENYL ISOTHIOCYANATE
| 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 | Detects and quantifies impurities (e.g., isomers, dehalogenated by-products) via gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., toluene, acetone) using capillary GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures trace water by coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Chloride Content | Ion Chromatography (IC) | Quantifies inorganic chloride ions after sample hydrolysis and dilution, using suppressed conductivity detection. |
| Heavy Metals | ICP-OES | Determines total heavy metal content (Pb, Cd, Hg, As) after acid digestion, via multi-element optical emission spectroscopy. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against standard reference. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after high-temperature ashing and weighing. |
| Organic Volatile Impurities (OVI) | GC-MS | Identifies and quantifies unknown volatile impurities using gas chromatography coupled with mass spectrometric detection. |
| pH of Aqueous Suspension | pH Meter | Measures acidity/basicity of saturated aqueous suspension using calibrated pH electrode. |
| Bulk Density | USP <616> Tap Density Method | Determines mass per unit volume after standardized mechanical tapping of a powder sample in a graduated cylinder. |
