Manufacturing Quality Control of Tosyl cyanide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in a methanol-based solvent system. |
| Residue on Ignition | Gravimetric Analysis | Mass of non-volatile residue determined after high-temperature ashing of a weighed sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals by atomization and absorption measurement at characteristic wavelengths after acid digestion. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Titration using silver nitrate with silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Sulfate Impurity | Ion Chromatography (IC) | Separation and quantification of sulfate anions using anion-exchange column and conductivity detection. |
| Free Cyanide | Spectrophotometry (Pyridine-Pyrazolone method) | Formation of colored complex with pyridine and pyrazolone reagents, measured at ~578 nm absorbance. |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed visually or automatically as solid-to-liquid phase change in a calibrated capillary apparatus. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against specified criteria under controlled lighting conditions. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Organic Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Identification and quantification of residual solvents by thermal desorption and mass spectral detection. |
| Particle Size Distribution | Laser Diffraction | Measurement of scattered light intensity from dispersed particles to calculate size distribution based on Mie theory. |
