Manufacturing Quality Control of ISOPROPYLTHIOUREA
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210-230 nm, comparing peak area against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with water in a methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C in a platinum crucible and weighing the non-volatile inorganic residue after cooling. |
| Heavy Metals (as Pb) | Colorimetric Limit Test | Reaction with thioacetamide under controlled pH to form colored metal sulfide complexes, compared visually to lead standard solutions. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection. |
| Sulfate Impurity | Turbidimetric Method | Precipitation of sulfate as barium sulfate in acidic medium; quantification by measuring turbidity at 420 nm. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary tube apparatus per USP <741>. |
| Appearance (Color and Clarity) | Visual Inspection | Comparison of solution clarity and color against standard references (e.g., APHA or Hazen scale) in specified solvent and concentration. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and detection of residual solvents using capillary GC with flame ionization detection and internal standard calibration. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode and pH meter. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light by chiral molecules in solution at specified concentration, temperature, and wavelength (589 nm). |
| Related Substances | HPLC-DAD | Separation and identification of structurally related impurities using HPLC with diode array detection and comparison to reference standards. |
