Manufacturing Quality Control of 1,3-Diphenyl-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. |
| Appearance | Visual Inspection | Assessment of physical state and color under controlled lighting against a white background; product should be off-white to light yellow crystalline powder. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Loss on Drying | Gravimetric (Oven Drying) | Measurement of mass loss after drying at 105 C for 2 hours, indicating volatile impurities or residual solvents. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Mass of non-volatile inorganic residue remaining after ignition at 700-800 C, reflecting inorganic contaminants. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption measurement of total heavy metals after wet digestion, reported as lead equivalent per USP <231>. |
| Sulfate Impurity | Turbidimetric Method | Quantification based on barium sulfate precipitate formation and measurement of turbidity at 420 nm. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally related impurities using gradient HPLC with diode-array detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine trace water content. |
| Organic Volatile Impurities | GC-FID | Detection and quantification of residual solvents using gas chromatography with flame ionization detection. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a 1:10 w/v suspension in purified water using calibrated pH electrode. |
