Manufacturing Quality Control of 3,4-Difluoro-2-methoxyphenylacetic acid
| Milestone | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, state, and presence of visible foreign particles under natural light or standard lighting. |
| Identification | Infrared Spectroscopy (IR) | Compare the sample with a standard spectrum by analyzing characteristic absorption peaks to confirm functional groups in the molecular structure (e.g., carboxyl, aromatic rings, C-F, C-O, etc.). |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyze the chemical shift and coupling splitting patterns of hydrogen atoms to confirm the compound structure and the position of substituents. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase column (e.g., C18) with a UV detector (typically at 254 nm or 280 nm), and quantify the main component using external or internal standard methods. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate the main peak and impurity peaks through gradient elution, detect and quantify residual intermediates and degradation products, and calculate the total impurity content. |
| Residual Solvents | Gas Chromatography (GC) | Detect residual organic solvents (e.g., methanol, ethanol, dichloromethane) using headspace or solution sampling methods. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Method | Heat the sample at a specified temperature (e.g., 60–105°C) for a certain period to determine the mass percentage lost due to moisture or volatile substances. |
| Water Content | Karl Fischer Titration | Quantitatively determine the water content in the sample using the reaction between iodine and sulfur dioxide in a pyridine/methanol system, suitable for detecting trace amounts of water. |
| Melting Point | Capillary Melting Point Method | Determine the temperature range from initial melting to complete melting using a melting point apparatus, used for auxiliary identification and purity assessment. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Determine the residual levels of heavy metals such as lead, cadmium, mercury, and arsenic after sample digestion, complying with pharmacopoeia or relevant regulatory limits. |
| Residue on Ignition | Sulfate Ash Method | After high-temperature incineration, add sulfuric acid to the sample and weigh the residue to assess the content of inorganic impurities. |
