Manufacturing Quality Control of 3-Methoxy-4-methylbenzoic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, state, and presence of visible impurities under natural light or standard illumination. |
| Melting Point | Melting Point Determination (Capillary Method) | Determine the temperature range from initial melting to complete melting using a melting point apparatus, used to assess purity and consistency of the substance. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase C18 column with a UV detector (e.g., 254 nm), employing methanol-water or buffer solution as the mobile phase, and external standard method for quantitative analysis of the main component. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Same as above, separate and detect possible synthetic intermediates, by-products, or degradation impurities through gradient elution, and calculate the area of each impurity peak. |
| Moisture | Karl Fischer Method (Karl Fischer Titration) | Measure the total amount of bound and free water in the sample using a KF titrator, suitable for trace moisture analysis. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Method | Dry the sample at a specified temperature (e.g., 105°C) for a certain period, and calculate the volatile matter content based on the mass difference before and after drying. |
| Residue on Ignition (Sulfated Ash) | Weight Method | Carbohydrate the sample at high temperature, then add sulfuric acid and ignite until constant weight, the mass of the residual inorganic material is used as an indicator. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Digest the sample and determine the content of heavy metals such as lead, cadmium, mercury, and arsenic, ensuring compliance with pharmacopoeia or safety standards. |
| Solubility | Solubility Test | Add the sample to solvents such as water, ethanol, methanol, ethyl acetate, shake and observe its solubility to determine physicochemical properties. |
| Structure Confirmation | Fourier Transform Infrared Spectroscopy (FT-IR) | Determine the infrared absorption spectrum of the sample and compare it with standard spectra to confirm the presence of functional groups (such as carboxyl, methoxy, and aromatic rings). |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Analyze the ¹H-NMR and ¹³C-NMR spectra to verify the molecular structure and ensure it matches the target compound. |
| Polymorphic Analysis | X-ray Diffraction (XRD) | Analyze the crystalline structure of solid samples, used for polymorphic studies or control of crystallinity consistency between batches (e.g., for formulation development). |
