Manufacturing Quality Control of 4-Chloro-2-mercaptobenzothiazole
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and detection of impurities using gradient HPLC with UV detection; identification and quantification relative to main peak. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine water content based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to combust organic matter, then weighing inorganic residue after cooling in desiccator. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection by plasma excitation and optical emission spectroscopy after acid digestion and dilution. |
| Chloride Impurity | Potentiometric Titration | Titration with silver nitrate using silver electrode to detect endpoint via potential change from AgCl precipitation. |
| Sulfur Content | Oxidative Combustion followed by Ion Chromatography | Complete combustion to sulfate, followed by ion chromatographic separation and conductivity detection of SO4(2-). |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary apparatus per USP <741>. |
| Organic Volatile Impurities | GC-FID | Separation by gas chromatography and quantification via flame ionization detection using internal standard calibration. |
| pH of Aqueous Suspension | pH Meter Measurement | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as function of angle to calculate particle size distribution in dispersed slurry. |
| Bulk Density | Graduated Cylinder Method | Determination of mass per unit volume after controlled pouring and gentle tapping of sample into standardized cylinder. |
