Manufacturing Quality Control of N-THIONYLANILINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., aniline, benzenesulfinic acid, N-phenylhydroxylamine) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., toluene, ethanol, ethyl acetate) using capillary GC with flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr after acid digestion, based on atomic emission intensity at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separation and quantification of sulfate ions using anion-exchange column with suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature using calibrated capillary apparatus under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against standard white background under controlled lighting conditions. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities (e.g., residual sulfonic acids) with standardized NaOH solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile inorganic residue remaining after high-temperature ashing (700-800 C) of sample in platinum crucible. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral impurities or enantiomeric excess, using sodium D-line at specified concentration and path length. |
