Industrial Applications of 1,2-BIS(DICHLOROMETHYL)BENZENE
| Industry | Application | Process |
|---|---|---|
| Pesticides | Key intermediate in the synthesis of the organophosphorus insecticide folithion | Reacted with sodium sulfide, sulfur monochloride, and other reagents; followed by cyclization and chlorination to produce folithion |
| Pesticides | One precursor in the synthesis of the organophosphorus insecticide terbufos | Used as a starting material in multistep synthesis; the terbufos molecular scaffold is constructed via substitution and oxidation reactions |
| Pharmaceuticals | Potential drug synthesis intermediate (research stage) | Employed to construct chlorinated benzothiazole or benzoxazole heterocyclic structures; applied at laboratory scale for screening antitumor or antibacterial compounds |
Manufacturing Quality Control of 1,2-BIS(DICHLOROMETHYL)BENZENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against certified reference standard under optimized chromatographic conditions. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration measuring water content via iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of non-volatile inorganic residue after high-temperature ashing at 750 C. |
| Chloride Impurities | Ion Chromatography (IC) | Separation and quantification of chloride anions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals by flame or graphite furnace AAS after acid digestion and matrix matching. |
| Volatile Organic Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and semi-quantification of structurally related impurities (e.g., isomers, dechlorinated analogs) via retention time and mass spectral match. |
| Melting Point | Capillary Melting Point Determination | Observation of solid-to-liquid phase transition temperature range using calibrated capillary apparatus. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Solvent Residues (e.g., toluene, xylene) | Headspace Gas Chromatography (HS-GC) | Quantification of residual solvents by equilibrium headspace sampling followed by GC-FID analysis. |
| Particle Size Distribution | Laser Diffraction | Measurement of particle size distribution in suspension using Mie scattering theory and optical detection. |
| Specific Optical Rotation | Polarimetry | Determination of optical activity using sodium D-line light through a defined path length and concentration. |
