Manufacturing Quality Control of 1-ACETYL-3-THIOSEMICARBAZIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration where iodine reacts stoichiometrically with water in a pyridine-methanol solvent system. |
| Residue on Ignition | Gravimetric Analysis | Heating the sample to 700-800 C to combust organic matter, then weighing the inorganic residue after cooling in a desiccator. |
| Heavy Metals (as Pb) | Colorimetric Limit Test (Thioacetamide Method) | Reaction of heavy metal ions with thioacetamide under controlled pH to form colored metal sulfide complexes, compared visually to a lead standard. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions on an anion-exchange column with suppressed conductivity detection. |
| Sulfate Impurity | Barium Sulfate Turbidimetry | Precipitation of sulfate as BaSO4 in acidic medium; turbidity measured spectrophotometrically at 420 nm. |
| Related Substances | HPLC-DAD | Separation by reversed-phase HPLC with diode-array detection to identify and quantify structurally related impurities based on retention time and spectral match. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, observed visually through a calibrated capillary tube. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measurement of hydrogen ion activity using a calibrated glass electrode and reference electrode in a 1% w/v aqueous suspension. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and quantification of residual solvents using capillary GC with flame ionization detection. |
| Iron (Fe) Content | Atomic Absorption Spectroscopy (AAS) | Quantification of iron by measuring absorbance of ground-state Fe atoms at 248.3 nm in an air-acetylene flame. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Measurement of mass loss upon heating to 105 C for 2 hours under ambient atmosphere to determine volatile content. |
