Manufacturing Quality Control of 4-Chlorobenzoic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | By measuring the infrared absorption spectrum of the sample and comparing it with the standard spectrum, the presence of characteristic functional groups of p-chlorobenzoic acid (such as carboxyl group, benzene ring, C–Cl bond, etc.) can be confirmed. |
| High-Performance Liquid Chromatography (HPLC) Retention Time Comparison | Under specific chromatographic conditions, compare the retention time of the sample with that of the reference standard to perform a preliminary identification. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase C18 column, methanol-water or acetonitrile-water as the mobile phase, and a UV detector (typically at 230–280 nm), the content of p-chlorobenzoic acid is quantitatively determined by external standard method or internal standard method. |
| Acid-Base Titration Method | Utilizing the acidity of the carboxyl group in p-chlorobenzoic acid, titrate with a standard sodium hydroxide solution in non-aqueous or aqueous conditions. The content is calculated based on the amount of alkali consumed. This method is suitable for samples with high purity and no significant interfering acidic impurities. | |
| Related Substances / Impurity Check | High-Performance Liquid Chromatography (HPLC) | Use gradient or isocratic elution programs to separate and detect possible impurities (such as p-chlorobenzaldehyde, p-chlorobenzyl alcohol, unreacted raw materials, etc.). Quantitative analysis is usually performed using area normalization or main component self-control method with correction factors. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Atmospheric Pressure Constant Temperature Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight, and measure the percentage of mass loss to assess moisture and volatile substance content. |
| Ignited Residue | High-Temperature Ashing Method | After carbonization, the sample is ignited at 700–800°C, and the mass of the residual inorganic material is measured to control the total amount of inorganic impurities. |
| Heavy Metals | Sulfur Acetamide Colorimetric Method (or Atomic Absorption Spectrometry AAS/ICP-MS) | Process the sample according to the pharmacopoeia method, react with sulfur acetamide under acidic conditions to form a colored precipitate, and determine the total amount of heavy metals (such as lead, cadmium, mercury, arsenic) by visual colorimetry or instrumental measurement. Modern methods often use AAS or ICP-MS for element-specific quantitative analysis. |
| pH Value (if in solution) | pH Meter Measurement Method | Measure the pH of a certain concentration of p-chlorobenzoic acid solution (e.g., 1% aqueous solution or appropriate solvent system) using a calibrated pH meter to reflect the free acid state and possible alkaline impurities. |
