Manufacturing Quality Control of 4-METHYLPHENYLTHIOUREA
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-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 by observing sample in a clear glass container under controlled white light. |
| 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 residue remaining after ignition at 600 C, reflecting inorganic impurities. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy measurement of total heavy metals after wet digestion and comparison to lead standard. |
| Sulfate Impurity | Turbidimetric Method | Formation of barium sulfate precipitate in acidic medium; quantification via optical density measurement. |
| Related Substances | HPLC-DAD | Separation and detection of structurally related impurities using gradient HPLC with diode-array detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on iodine consumption in pyridine-methanol solvent system. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a 1% w/v aqueous suspension using calibrated pH electrode per EP 2.2.3. |
| Organic Volatile Impurities | GC-FID | Headspace or direct injection GC with flame ionization detection for residual solvents such as methanol, acetone, or toluene. |
