| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate in the synthesis of antimicrobial agents | Used in Grignard reactions and bromination |
| Agrochemicals | Key raw material for insecticide production | Applied in alkylation and substitution reactions |
| Materials | Used in the preparation of conductive polymers | Applied in oxidative polymerization and chemical vapor deposition |
| Fine Fragrances | Precursor for fragrance compound synthesis | Used in reduction and esterification reactions |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separates and detects impurities based on relative retention times and response factors; identification via mass spectral library match when using MS. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatiles are equilibrated in headspace vial and quantified by GC-FID using calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in sample. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., residual HCl) using standardized sodium hydroxide solution and potentiometric endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion by measuring elemental ion signals at specific mass-to-charge ratios. |
| Sulfur Content | Combustion IC | Sample combusted to SO2, converted to sulfate, and detected conductometrically or by ion chromatography. |
| Chloride Ion | Ion Chromatography (IC) with conductivity detection | Separation of anions on ion-exchange column followed by quantitative detection via electrical conductivity. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against standard reference under controlled lighting conditions. |
| Density | Digital Density Meter | Measures oscillation period of U-tube filled with sample to determine density at specified temperature. |
| Refractive Index | Refractometry | Determines refractive index by measuring angle of light refraction at air-sample interface using calibrated prism. |
| Boiling Range | Distillation (Micro-Scale ASTM D1078) | Measures temperature interval over which 5% to 95% of sample distills under controlled vacuum and heating rate. |
