Manufacturing Quality Control of 3-Amino-4-hydroxybenzenesulphonamide
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state (e.g., white to pale yellow crystalline powder), presence of foreign matter, or lumping and other physical characteristics. |
| Purity | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase chromatographic column with an appropriate mobile phase (e.g., methanol-buffer salt system) for separation, and quantify the main component peak area using UV detection (e.g., 254 nm), then calculate purity. |
| Content Determination | HPLC External Standard Method / Potentiometric Titration | HPLC Method: Calculate content by comparing peak areas with those of reference standards; Potentiometric Titration: Utilize the basic amino group in the compound, titrate with a standard acid solution, and determine the endpoint via sudden potential change. |
| Loss on Drying | Drying Method (105°C, constant weight) | Accurately weigh the sample into a tared crucible, dry at 105°C until constant weight, and calculate the percentage loss in weight to assess moisture and volatile content. |
| Residual Ash | High-Temperature Incineration (600–800°C) | Charm the sample in a crucible at high temperature until constant weight, and determine the mass percentage of residual inorganic impurities (e.g., metal oxides). |
| Heavy Metals | Heavy Metal Test Method from the Chinese Pharmacopoeia | Typically uses thioacetamide method or atomic absorption spectrometry (AAS) to control total levels of harmful metals such as lead, cadmium, mercury, and arsenic. |
| Impurities Related Substances | HPLC Gradient Elution Method | Optimize chromatographic conditions to separate the main component from potential impurities (e.g., synthesis by-products, degradation products). Control impurity limits using area normalization or self-reference methods. |
| pH Value | pH Meter Measurement (in aqueous solution or buffer) | Prepare a solution of defined concentration, then directly measure pH using a calibrated pH meter, reflecting the acidity/alkalinity of the sample and possible free acids/bases. |
| Melting Point | Capillary Melting Point Determination | Determine the temperature range from initial melting to complete melting using a melting point apparatus, used for identification and assessment of crystalline purity. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace injection or direct injection, separate volatile organic solvents (e.g., methanol, ethanol, DMF) using polar or non-polar capillary columns, and quantitate with FID or ECD detectors. |
