| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of antidepressant drugs | Used as an intermediate in chemical reactions |
| Pesticides | Synthesis of fungicides | Reacted with other pesticide components |
| Dyes | Dye intermediate | Applied in coupling and oxidation reactions |
| Fragrances | Synthesis of specialty aroma compounds | Applied in condensation and substitution reactions |
| Polymer materials | Initiator or catalyst | Facilitates polymerization reactions |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., regioisomers, debrominated analogs) via gradient HPLC-UV against qualified impurity standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., ethanol, toluene, DMF) by headspace GC with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni, As) 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. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid phase transition using calibrated capillary apparatus per USP <741>. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature incineration (700-800 C) followed by precise weighing of residual residue. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against established visual reference standards. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity (if applicable) by determining rotation of plane-polarized light in solution using sodium D-line (589 nm). |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution by measuring angular scattering intensity of laser beam passed through dispersed sample. |
| Bulk Density | Tap Density Tester | Determines mass per unit volume of powder in a standardized cylinder after mechanical tapping per USP <616>. |
