Manufacturing Quality Control of 3-Amino-4-chlorobenzoic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | Determines the infrared absorption spectrum of the sample and compares it with the standard reference spectrum to confirm the presence of characteristic functional groups of 3-Amino-4-chlorobenzoic acid, such as carboxyl, amino, aromatic ring, and C–Cl bond absorption peaks. |
| High-Performance Liquid Chromatography (HPLC) Retention Time Comparison | Compares the retention time of the test sample with that of the reference substance under specific chromatographic conditions for preliminary identification. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with phosphate buffer-methanol or acetonitrile as the mobile phase and UV detection (typically around 254 nm). The content of the main component is calculated using external standard method. This method offers high specificity and good reproducibility, making it suitable for quantitative analysis of active pharmaceutical ingredients. |
| Acid-Base Titration | Utilizes the acidity of the carboxyl group; titrates with standardized sodium hydroxide solution in either non-aqueous or aqueous medium, determining the endpoint via potentiometry or indicator method, and calculates the content. Suitable for samples with high purity and minimal interfering impurities. | |
| Related Substances (Impurity Testing) | High-Performance Liquid Chromatography (HPLC) | Employs gradient or isocratic elution to separate and detect potential process-related impurities (e.g., unreacted raw materials, intermediates) and degradation products (e.g., dechlorinated or oxidized compounds). Quantification is typically performed using area normalization or the main component self-control method with correction factors. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Constant-Pressure Drying Method | Dries the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, measuring the percentage of mass loss to assess moisture and volatile substances content. |
| Residue on Ignition | Gravimetric Method | After high-temperature ignition (typically 700–800°C), the residual inorganic matter is weighed to control inorganic impurities (e.g., metal catalyst residues). |
| Residual Solvents | Gas Chromatography (GC) | Uses headspace injection or direct injection with polar or non-polar capillary columns and FID detection to determine organic solvents (e.g., toluene, dichloromethane, DMF) potentially remaining from synthesis processes. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, quantifies harmful elements such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmacopoeial limits. |
| pH Value | pH Meter Method | Prepares an aqueous solution of specified concentration (e.g., 1%), then measures its pH using a calibrated pH meter, reflecting the presence of free acid or basic impurities. |
