Industrial Applications of 4-CHLOROPHENYL CHLOROTHIONOFORMATE
| Industry | Application | Process |
|---|---|---|
| Pesticides | Intermediate for organophosphorus insecticides (e.g., chlorpyrifos, methyl chlorpyrifos) | Condensed with amine compounds such as 2-amino-5-chlorophenol, followed by cyclization and hydrolysis to synthesize phosphorus-containing heterocyclic structures |
| Pharmaceuticals | Intermediate for anticancer drugs (e.g., precursors of certain protein kinase inhibitors) | Participates in nucleophilic substitution reactions to construct C–S bonds or serves as a thiocarbonylating reagent to introduce chlorothioformate groups |
| Materials Science | Functional monomer for polymers (used in synthesizing sulfur-containing flame retardants or heat-resistant polymers) | Undergoes condensation polymerization with diols or diamines to produce specialty polymers containing thiocarbonate linkages |
Manufacturing Quality Control of 4-CHLOROPHENYL CHLOROTHIONOFORMATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and detector. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Volatile organic impurities are vaporized in a sealed vial, injected into GC, and quantified by calibration curves. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities (e.g., HCl, sulfonic acids) using standardized sodium hydroxide and phenolphthalein indicator. |
| Chloride Ion Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column followed by quantitative detection via changes in electrical conductivity. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of metals in high-temperature plasma; elemental quantification via characteristic emission wavelengths. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash method) | Sample is charred, treated with sulfuric acid, ignited at 700-800 C, and residual inorganic ash is weighed. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample solution color intensity against platinum-cobalt standards or absorbance measurement at specified wavelength. |
| Specific Gravity | Digital Density Meter (Oscillating U-tube principle) | Density derived from resonant frequency shift of a vibrating U-shaped tube filled with sample at controlled temperature. |
| Refractive Index | Refractometry (Abbe type) | Measurement of light refraction angle at air-sample interface to determine refractive index at specified temperature and wavelength (589 nm). |
| Non-Volatile Residue | Evaporation and Gravimetric Weighing | Sample is evaporated to dryness under controlled conditions, and residue mass is determined by difference in weight before and after evaporation. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation of structurally similar impurities on a reversed-phase column; detection and quantification via UV absorbance at optimized wavelength. |
