Manufacturing Quality Control of 4-Methylsulphonylphenylacetic acid
| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with standard spectra to confirm the presence of characteristic functional groups (such as carboxyl, sulfonate, and aromatic rings) of 4-methanesulfonamido benzoic acid. |
| Nuclear Magnetic Resonance Hydrogen Spectroscopy (¹H NMR) | Analyze the hydrogen atoms in the compound using nuclear magnetic resonance technology, verifying its molecular structure through chemical shift, integral area, and coupling constants. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase C18 column with an appropriate mixture of water and organic solvent (such as methanol or acetonitrile) as the mobile phase. Detect using a UV detector (typically at wavelengths of 220–260 nm), and quantify using external standard or internal standard methods. |
| Related Substances (Impurities) Check | High-Performance Liquid Chromatography (HPLC) | Use gradient or isocratic elution programs to separate and detect potential process impurities and degradation products. Quantify using area normalization or the main component self-reference method with correction factors. |
| Residual Solvents | Gas Chromatography (GC) | According to ICH Q3C guidelines, use headspace or direct injection methods, and detect residual organic solvents (such as toluene, dichloromethane, ethanol, etc.) using a Flame Ionization Detector (FID). |
| Drying Loss | Thermogravimetric Analysis (TGA) or Atmospheric Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is reached, and determine the percentage loss due to moisture or other volatile components. |
| Residue on Ignition | Gravimetric Method | Heat the sample at high temperature (usually 700–800°C) to completely decompose the organic matter, weigh the remaining inorganic residue, and assess the total amount of inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Treat the sample according to pharmacopoeia methods and measure the residual amounts of heavy metals such as lead, cadmium, mercury, and arsenic to ensure they meet safety limits. |
| pH Value (if applicable) | pH Meter Method | Prepare a solution or suspension of a certain concentration, and measure its acidity or alkalinity using a calibrated pH meter. |
| Melting Point | Capillary Melting Point Determination | Determine the melting range from initial melting to complete melting using a melting point apparatus, serving as an auxiliary indicator for purity and identity. |
