Manufacturing Quality Control of (3,4-Dimethoxyphenyl)acetic acid
| Test Item | Common Testing Method | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and physical state of the sample under natural or standard lighting to determine if it is a white to off-white crystalline powder, and check for visible impurities. |
| Identification | Infrared Spectroscopy (IR) | Prepare a pellet with sample and potassium bromide, record the infrared absorption spectrum, and compare it with the reference spectrum to confirm consistency of functional groups and molecular structure. |
| Proton Nuclear Magnetic Resonance (¹H-NMR) | Dissolve the sample in a deuterated solvent (e.g., DMSO-d6), and verify molecular structure based on characteristic peak positions and integral areas. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (typically at 280–290 nm), and a mobile phase of water-methanol or water-acetonitrile. Quantify the main component using external or internal standard method. |
| Impurity Testing (Related Substances) | High-Performance Liquid Chromatography (HPLC) | Same as above; use gradient elution to separate impurity peaks, then calculate the levels of individual and total impurities to assess purity. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Method | Dry the sample at a specified temperature (e.g., 105°C) to constant weight; calculate the content of moisture and volatile components based on weight loss. |
| Sulfated Ash | Sulfated Ash Residue Method | Char the sample at high temperature, treat with sulfuric acid, then ignite to constant weight. Weigh the residue to determine the content of inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Digest the sample and measure the levels of heavy metal elements such as lead, cadmium, mercury, and arsenic, ensuring compliance with pharmacopoeial or customer-specified limits. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection to detect organic solvents (e.g., methanol, ethanol, acetone) that may remain from the manufacturing process. |
| Melting Point | Melting Point Apparatus | Determine the melting temperature range using an automated or capillary melting point apparatus, and compare with literature values (approximately 178–182°C) to assess purity. |
