Manufacturing Quality Control of 4-Chloro-3-nitro-5-sulphamoylbenzoic acid
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity Test | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column and a UV detector (e.g., 254 nm or set according to the maximum absorption wavelength). Quantifies the purity of the main component using external standard method or area normalization method. The mobile phase is typically a buffer salt–organic solvent system (e.g., phosphate buffer/acetonitrile). |
| Related Substances (Impurities) | HPLC with Gradient Elution | Employs a gradient elution program to separate the main peak from potential process impurities and degradation products. The relative content of each impurity is calculated based on peak areas, ensuring compliance with pharmacopoeial or internal quality standards. |
| Assay | HPLC External Standard Method / Potentiometric Titration | HPLC External Standard Method: A calibration curve is established using a reference standard of known concentration to calculate sample content. Potentiometric Titration: Based on the neutralization reaction between carboxylic acid groups and alkali; the endpoint is determined by a potential jump, suitable for assay of active pharmaceutical ingredients. |
| Loss on Drying | Drying to Constant Weight at 105°C | A weighed sample is dried at 105°C until constant weight is achieved. The percentage weight loss is calculated to assess moisture and volatile content. |
| Sulfated Ash (Residue on Ignition) | High-Temperature Ashing (600–800°C) | The sample is completely ashed in a muffle furnace at high temperature. The residual inorganic matter is weighed to monitor inorganic impurities or catalyst residues. |
| Heavy Metals | Heavy Metals Test as per Chinese Pharmacopoeia (Method I) | After digestion of the sample, it reacts with thioacetamide reagent to produce coloration. The intensity is compared with that of a lead standard solution to ensure total heavy metals (calculated as Pb) do not exceed specified limits. |
| Residual Solvents | Gas Chromatography (GC-FID or GC-MS) | Headspace or direct injection is used, with separation on capillary columns such as DB-624, and detection by FID or MS to quantify common residual organic solvents (e.g., methanol, ethyl acetate, DMF, etc.). |
| pH Value | pH Meter Measurement | Aqueous solution of defined concentration (e.g., 1% w/v) is prepared. After calibrating the pH meter, the pH is measured directly to reflect acidity/basicity and possible presence of free acid or salt forms. |
| Melting Point | Capillary Melting Point Apparatus | A digital melting point apparatus is used to observe the temperature range from initial melting to complete melting, assessing crystalline purity and structural consistency. |
| Structural Confirmation | Infrared Spectroscopy (IR), Nuclear Magnetic Resonance (NMR), Mass Spectrometry (MS) | IR confirms characteristic functional group absorption peaks; ¹H/¹³C NMR analyzes hydrogen and carbon environments; MS (ESI or EI) verifies molecular ion and fragment ions. Used collectively to confirm chemical structure. |
