Manufacturing Quality Control of 1-(3,4-DICHLOROPHENYL)-2-THIOUREA
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., acetone, methanol, ethyl acetate) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent; water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection after acid digestion; quantification by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by abrupt potential change due to AgCl precipitation. |
| Sulfur Content | Oxidative Combustion followed by Ion Chromatography | Complete combustion to sulfate, absorption in H2O2, then quantification of SO4(2-) by IC conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range over which solid converts to liquid. |
| Loss on Drying | Gravimetric (105 C, 2 h) | Mass loss measured after drying under controlled temperature and time, reflecting volatile and moisture content. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate volume-based size distribution. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
| Residue on Ignition | Gravimetric (500-600 C) | Mass of non-volatile inorganic residue remaining after high-temperature ashing of sample in platinum crucible. |
