Manufacturing Quality Control of Ethyl 3,4-dihydroxybenzoate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | By measuring the infrared absorption spectrum of the sample and comparing it with a reference spectrum, confirm whether the characteristic functional group absorption peaks (e.g., phenolic hydroxyl, ester group, benzene ring, etc.) of ethyl 3,4-dihydroxybenzoate are consistent. |
| High-Performance Liquid Chromatography (HPLC) Retention Time Comparison | Under specific chromatographic conditions, inject both the sample and reference standard simultaneously, and compare whether the retention time of the main peak is identical for preliminary identification. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Utilize a reversed-phase C18 column with a mobile phase of methanol-water or acetonitrile-water (often containing a small amount of acid to adjust pH), and detect using a UV detector (typically at 280–320 nm wavelength). Quantify the main component using external standard or internal standard methods. |
| Ultraviolet-Visible Spectrophotometry (UV-Vis) | Utilize the maximum absorbance at a specific wavelength (e.g., approximately 295 nm) and determine the concentration of ethyl 3,4-dihydroxybenzoate in solution via a standard calibration curve. Suitable for rapid quantification of high-purity samples. | |
| Related Substances (Impurities) Check | High-Performance Liquid Chromatography (HPLC) | Use gradient or isocratic elution to separate the main component from potential impurities (e.g., residual starting materials, degradation products, etc.). Control the limits of individual impurities using area normalization or the main component self-reference method with correction factors. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Atmospheric Drying Method | Dry the sample to constant weight at a specified temperature (e.g., 105°C) and calculate the percentage of mass loss to control moisture and volatile substances. |
| Residue on Ignition | High-Temperature Ignition Method | After carbonization, ignite the sample in a furnace at 700–800°C and weigh the residual inorganic material to evaluate the level of inorganic impurities. |
| Heavy Metals | Thioacetamide Method (Colorimetric) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | The traditional pharmacopoeial method uses thioacetamide color development and colorimetry to determine total heavy metals; ICP-MS enables precise determination of specific elemental residues such as lead, arsenic, cadmium, and mercury. |
| pH Value (if applicable to solution formulations) | pH Meter Method | Directly measure the pH of the test solution using a calibrated pH meter to ensure it falls within the specified range, reflecting acid-base stability. |
