Manufacturing Quality Control of 2,3-Dichlorobenzoic acid
| Test Item | Common Test Method | Method Summary |
|---|---|---|
| Purity/Content Assay | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with methanol-water or acetonitrile-water as the mobile phase, and a UV detector (typically at 230–280 nm) to detect 2,3-dichlorobenzoic acid. The main component content is calculated using external standard or area normalization methods, suitable for purity control of active pharmaceutical ingredients and intermediates. |
| Related Substances (Impurity) Testing | High-Performance Liquid Chromatography (HPLC) | Employs a gradient elution program to separate the main peak from potential impurities (such as isomers, degradation products, etc.). Impurity levels are evaluated by comparing individual impurity peak areas to the main peak area, ensuring compliance with pharmacopoeial or internal quality control standards. |
| Melting Point Determination | Capillary Melting Point Method | The sample is packed into a capillary tube and heated at a specified rate in a melting point apparatus. The temperature range from initial melting to complete melting is recorded, used to assess compound purity and crystal form consistency. The typical melting point of 2,3-dichlorobenzoic acid is approximately 156–158 °C. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Constant Temperature Atmospheric Drying | The sample is dried to constant weight at a specified temperature (e.g., 105 °C), and the percentage weight loss is measured to control moisture and volatile impurity content. |
| Sulfated Ash/Residue on Ignition | High-Temperature Ignition Method | The sample is charred and then ignited at 700–800 °C in a high-temperature furnace until constant weight. The remaining inorganic residue is weighed to determine inorganic impurities or catalyst residues. |
| pH Value (if prepared as solution) | pH Meter Method | The sample is dissolved in water to a specified concentration (e.g., 1%), and the pH is measured using a calibrated pH meter to reflect free acid content and possible acidic or basic impurities. |
| Infrared Spectroscopic Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Sample is prepared as a KBr pellet or analyzed via ATR. The infrared spectrum is collected and compared with reference spectra for characteristic absorption peaks (e.g., carboxylic O–H, C=O, C–Cl), used for structural confirmation and authenticity identification. |
| Residual Solvents | Gas Chromatography (GC) | Headspace or direct injection is used, with separation on a polar capillary column such as DB-624 and detection by FID. This method detects residual organic solvents (e.g., toluene, dichloromethane) that may remain from the synthesis process. |
