Manufacturing Quality Control of 3,4,5-Trimethoxy benzoic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and form (usually a white to light yellow crystalline powder) to determine whether it conforms to the standard description. |
| Melting Point | Capillary Melting Point Method | Determine the melting temperature range (literature value approximately 198–202°C) using a melting point apparatus, to evaluate purity and consistency of the crystal structure. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a C18 chromatographic column, with methanol/water or buffer salt system as the mobile phase, and a UV detector (~270 nm) for quantitative determination of the main component. |
| Related Substances (Impurities) | HPLC (Gradient Elution) | Separate the main peak and potential impurity peaks by optimizing the gradient program, and calculate the content of each impurity using area normalization or external standard method. |
| Drying Loss | Drying Method (105°C, constant weight) | Dry the sample in an oven until constant weight, calculate the percentage of mass loss to assess moisture and volatile substance content. |
| Residue on Ignition | High-Temperature Ashing Method (600–800°C) | After high-temperature incineration, weigh the residual inorganic material to evaluate the level of inorganic impurities or metal salt residues. |
| Heavy Metals | Sulfuric Acid Thioacetamide Method or ICP-MS | Determine the total content of heavy metals such as lead, arsenic, mercury, and cadmium using colorimetry or inductively coupled plasma mass spectrometry (ICP-MS). |
| pH Value | pH Meter Measurement (aqueous solution or appropriate solvent) | Dissolve the sample in a specified solvent (e.g., water or ethanol), and measure the pH using a calibrated pH meter to evaluate the acid-base properties. |
| Solubility | Solubility Test | Observe the solubility of the sample in specified solvents (water, ethanol, ether, etc.) to verify whether its physical properties meet the requirements of the pharmacopoeia or standard. |
| Infrared Spectral Identification | Fourier Transform Infrared Spectroscopy (FTIR) | Collect the infrared absorption spectrum of the sample and compare it with that of the reference standard or database to identify characteristic peaks (such as carboxyl, methoxy, and benzene ring vibration peaks). |
| Nuclear Magnetic Resonance Proton Spectrum Identification | ¹H-NMR | Confirm the proton environment in the molecular structure (such as methoxy, aromatic protons, and carboxylic acid protons) through nuclear magnetic resonance hydrogen spectrum for structural confirmation. |
