Manufacturing Quality Control of 4-Methylphenyl isothiocyanate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component using retention time and peak area against calibrated standard. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separates and detects impurities based on volatility and retention behavior relative to main peak. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric iodine reaction with sample in anhydrous methanol/pyridine medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals (e.g., Pb, Cd, Hg) by atomic absorption of characteristic wavelengths. |
| Chloride Content | Potentiometric Titration with Silver Nitrate | Measures chloride ions via precipitation titration monitored by silver electrode potential change. |
| Acidity (as HCl) | Acid-Base Titration | Determines acidic impurities by titration with standardized NaOH using phenolphthalein indicator. |
| Color | Visual Comparison or Hazen (APHA) Scale | Evaluates color intensity by comparing sample solution to platinum-cobalt standard solutions. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus. |
| Specific Optical Rotation | Polarimetry | Determines optical activity by measuring rotation angle of plane-polarized light passing through solution. |
| Residual Solvents | Gas Chromatography (GC) with Headspace | Quantifies volatile organic solvents by equilibrium headspace analysis and GC separation. |
| Sulfur Content | Combustion IC (Ion Chromatography) | Oxidizes sulfur to sulfate, then quantifies sulfate anion via ion chromatographic separation and conductivity detection. |
