Manufacturing Quality Control of 2-Methylbenzene-1-sulfonamide
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Visually examine the sample for color and physical state (e.g., white or off-white crystalline powder) to determine if it meets standard specifications. |
| Purity | High-Performance Liquid Chromatography (HPLC) | Separate sample components using a reversed-phase chromatographic column; quantify the main peak area via UV detector and calculate purity (typically required to be ≥98.0%). |
| Assay | HPLC External Standard Method or Titration | HPLC external standard method: compare peak area with that of a known concentration standard; titration method: acid-base titration to determine content of sulfonamide group. |
| Related Substances (Impurities) | HPLC Gradient Elution Method | Use gradient elution to separate the main peak from impurity peaks; calculate individual impurity levels by area normalization or self-dilution reference method according to specified limits. |
| Loss on Drying | Oven Drying Method (105°C to Constant Weight) | Dry the sample at 105°C until constant weight is achieved; calculate moisture and volatile content based on weight difference before and after drying (generally ≤0.5%). |
| Sulfated Ash | High-Temperature Ashing Method (700–800°C) | Ignite the sample at high temperature, weigh the residual inorganic matter, and assess total inorganic impurities (typically ≤0.1%). |
| Heavy Metals | Thioacetamide Method or ICP-MS | Thioacetamide colorimetric method to determine total heavy metals such as lead (expressed as Pb, ≤20 ppm); ICP-MS enables highly sensitive multi-element detection. |
| Residual Solvents | Headspace Gas Chromatography (GC) | Detect organic solvents possibly remaining from manufacturing (e.g., methanol, ethanol, toluene) using headspace GC, in compliance with ICH Q3C limits. |
| Melting Point | Capillary Melting Point Method | Determine the temperature range from initial melting to complete melting (literature value approximately 168–170°C), used for identification and preliminary purity assessment. |
| pH Value | pH Meter Measurement (aqueous solution or suspension) | Prepare an aqueous solution of defined concentration and measure pH using a calibrated pH meter to evaluate acidity or alkalinity (o-toluenesulfonamide aqueous solution is typically weakly acidic). |
