Manufacturing Quality Control of 1-(2-Chlorophenyl)-2-thiourea
| 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 quantification of impurities using gradient HPLC with UV detection; identification based on retention time relative to reference standards. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to volatilize organic matter, then weighing inorganic residue after cooling in desiccator. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of heavy metals after acid digestion, based on characteristic atomic emission intensities. |
| Chloride Impurity | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition temperature using calibrated capillary tube method per USP <741>. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of residual solvents via gas chromatography with flame ionization detection. |
| Sulfur Content | Oxidative Combustion followed by Ion Chromatography | Complete combustion to sulfate, followed by anion exchange separation and conductivity detection. |
| Appearance | Visual Inspection | Assessment of color and physical state (crystalline powder) against established reference under controlled lighting conditions. |
| pH of Aqueous Suspension | pH Meter Measurement | Measurement of pH in a defined water suspension (e.g., 1% w/v) using calibrated pH electrode per EP 2.2.3. |
| Bulk Density | Graduated Cylinder Method | Determination of mass per unit volume for freely settled powder in a standardized cylinder per ASTM D1895. |
