Manufacturing Quality Control of Rhodanine-3-acetic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system; endpoint detected amperometrically. |
| Residue on Ignition | Gravimetric Analysis | Sample is ignited at 700-800 C to oxidize organic matter; inorganic residue is weighed after cooling in a desiccator. |
| Heavy Metals (as Pb) | Colorimetric Limit Test with Thioglycolic Acid | Reaction of heavy metal ions with thioglycolic acid under buffered conditions forms colored complexes, compared visually to lead standard solutions. |
| Chloride Impurity | Potentiometric Titration with Silver Nitrate | Titration using AgNO3 solution; endpoint detected by potential change measured with silver/silver chloride electrode. |
| Sulfate Impurity | Turbidimetric Method | Precipitation of sulfate as BaSO4 in acidic medium; turbidity measured spectrophotometrically at 420 nm. |
| Related Substances | HPLC-DAD | Separation of impurities by reversed-phase HPLC with diode array detection; identification and quantification relative to main peak using retention time and spectral match. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually as the temperature range over which solid transforms to liquid under controlled heating rate. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Hydrogen ion activity measured using calibrated glass electrode and reference electrode in a 1% w/v aqueous solution. |
| Loss on Drying | Thermogravimetric Weighing | Weight loss measured after drying sample at 105 C for 2 hours under atmospheric pressure; reflects volatile content including residual solvents. |
| Iron (Fe) Content | Atomic Absorption Spectroscopy (AAS) | Quantification of Fe via absorption of specific wavelength light (248.3 nm) by ground-state Fe atoms in an air-acetylene flame. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and detection of residual solvents using capillary GC column and flame ionization detection with internal standard calibration. |
