Manufacturing Quality Control of M-TOLUENESULFONYL CHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Moisture Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., residual HCl or sulfonic acids) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample heated at 700-800 C to oxidize organic matter; inorganic residue weighed after cooling in desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance of ground-state atoms at element-specific wavelength. |
| Sulfate (as SO4) | Barium Chloride Precipitation (Gravimetric) | Precipitation of sulfate as BaSO4 under controlled pH and temperature, followed by filtration, drying, and weighing. |
| Chloride (as Cl-) | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode; endpoint detected by abrupt potential change due to AgCl precipitation. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as solid-to-liquid phase change under controlled heating rate. |
| Organic Impurities (Related Substances) | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation on reversed-phase column and quantification of structurally related compounds using UV absorption at 254 nm. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against white background under controlled lighting conditions. |
| Bulk Density | Graduated Cylinder Method (ASTM D1895) | Mass of sample poured into calibrated cylinder divided by its volume; measured under standardized tapping conditions. |
| Particle Size Distribution | Laser Diffraction (Dry Dispersion) | Analysis of light scattering pattern from dispersed particles to calculate size distribution based on Mie theory. |
