Manufacturing Quality Control of p-Acetylamino benzoic acid
| Test Item | Commonly Used Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectrophotometry (IR) | Determines the infrared absorption spectrum of the sample and compares it with standard spectra to confirm the presence of characteristic functional groups (e.g., carboxyl, amide, benzene ring), used for structural confirmation of compounds. |
| Identification Test | Retention Time Comparison by High-Performance Liquid Chromatography (HPLC) | Under specific chromatographic conditions, compares the retention time of the test sample with that of the reference standard as a preliminary identification basis. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with phosphate buffer-methanol or acetonitrile as the mobile phase. Detection is performed using a UV detector (typically at 240–260 nm wavelength). Quantification is carried out by external or internal standard method to accurately determine the content of the main component. |
| Related Substances (Impurity) Testing | High-Performance Liquid Chromatography (HPLC) | Employs gradient or isocratic elution to separate the main peak from potential impurities (e.g., p-aminobenzoic acid, paracetamol, oxidation or degradation products). Impurity limits are controlled using area normalization or a main component self-comparison method with correction factors. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Constant Weight Drying under Normal Pressure | The sample is dried at a specified temperature (e.g., 105 °C) until constant weight is achieved. The percentage of mass loss is measured to evaluate the content of moisture and volatile substances. |
| Residue on Ignition | High-Temperature Ignition Method | After carbonization, the sample is ignited at a high temperature (700–800 °C) in a muffle furnace. The remaining inorganic residue is weighed to control the total amount of inorganic impurities. |
| pH Value | pH Meter Method | A solution of specified concentration (e.g., 1%) is prepared and its acidity or alkalinity is measured using a calibrated pH meter, reflecting the presence of free acid or alkaline impurities. |
| Solution Clarity and Color | Visual Turbidity/Color Comparison Method or Spectrophotometry | The sample is prepared into a solution of specified concentration and compared with standard turbidity or color solutions to assess insoluble particles or colored impurities. |
| Residual Solvents | Gas Chromatography (GC) | Uses headspace or direct injection with an FID detector. Residual organic solvents possibly present from synthesis or purification (e.g., methanol, ethanol, acetone, dichloromethane) are detected according to pharmacopoeia methods. |
| Heavy Metals | Thioacetamide Method or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Detects harmful elemental residues such as lead, cadmium, mercury, and arsenic through colorimetry (thioacetamide color development) or high-sensitivity instrumental methods (ICP-MS), ensuring compliance with safety limits. |
