Industrial Applications of 2-CHLOROTHIOPHENOL
| Industry | Application | Process |
|---|---|---|
| Pesticides | Key intermediate for synthesizing organophosphorus insecticides (e.g., chlorpyrifos, methyl chlorpyrifos) | Reacted with phosphorus oxychloride or diethylamine, followed by cyclization and substitution to produce target pesticides |
| Pharmaceuticals | Intermediate for synthesizing antibacterial agents (e.g., sulfonamide derivatives) and antitumor drugs | Used in coupling reactions or as a thioetherification reagent to construct sulfur-containing heterocyclic structures |
| Dyes | Used to synthesize benzothiazole-based fluorescent brighteners and thioindigo dyes | Condensed with aldehydes to form the benzothiazole ring, or serves as a sulfur source in dye molecule synthesis |
| Rubber additives | Raw material for producing rubber accelerators (e.g., CBS, TBBS) | Reacted with cyclohexylamine and carbon disulfide to generate benzothiazole-based accelerators |
Manufacturing Quality Control of 2-CHLOROTHIOPHENOL
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity and Content Determination | High-Performance Liquid Chromatography (HPLC) | Uses a C18 reversed-phase column, with methanol/water or acetonitrile/water as the mobile phase. Detection is performed using a UV detector (254 nm). The content of o-chlorobenzenethiol is quantified by external or internal standard methods, offering good resolution and high accuracy. |
| Purity and Content Determination | Gas Chromatography (GC) | Employs a capillary column (e.g., DB-5) with an FID detector. Temperature programming is used for separation, suitable for samples with good volatility. Thermal stability should be considered to avoid decomposition. |
| Impurity Analysis | HPLC-MS / GC-MS | Mass spectrometry coupled methods can qualitatively and quantitatively detect process-related impurities (e.g., dimers, o-chlorophenol, unreacted starting material such as chlorobenzene), providing molecular weight and structural information with high sensitivity. |
| Moisture Determination | Karl Fischer Titration | Suitable for trace moisture analysis with high accuracy. Used to control trace water content in o-chlorobenzenethiol. Interference from sulfur-containing compounds should be avoided; appropriate solvents (e.g., methanol-pyridine system) should be selected. |
| Sulfur Content Determination | Oxygen Flask Combustion - Ion Chromatography / Combustion Iodometry | The sample is completely combusted in an oxygen flask, converting sulfur to sulfate. Sulfate is measured by ion chromatography or titrated using iodometry, to confirm whether the sulfur content meets the theoretical value (approximately 34.5%). |
| Appearance and Color | Visual Inspection / Color Measurement (APHA) | Observe sample as a colorless to pale yellow liquid. APHA colorimeter or color chart is used to assess color intensity, indicating the presence of oxidative or polymeric impurities. |
| pH Value (aqueous solution) | pH Meter Measurement | Dissolve the sample in an appropriate amount of water (or ethanol-water mixture), and measure the pH using a calibrated pH meter. O-Chlorobenzenethiol is weakly acidic (pH ≈ 5–6), useful for detecting alkaline impurities. |
| Boiling Point/Distillation Range | Distillation Method / Boiling Point Apparatus | Determine the atmospheric boiling point (approximately 215–218 °C) to assess purity. A wide distillation range or presence of low-boiling impurities suggests residual solvents or by-products. |
| Heavy Metal Residues | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine the content of heavy metals such as lead, cadmium, mercury, and arsenic, ensuring compliance with pharmacopoeia or chemical standards (e.g., ICH Q3D limits). |
| Chlorine Content Determination | Combustion Ion Chromatography / Coulometric Titration | After combustion, chlorine is converted to chloride ions and quantified by ion chromatography, or measured using coulometric titration for total chlorine content, verifying whether the chlorine content matches the theoretical value (approximately 43.8%). |
