| Explosives Industry | Gas absorbent | Used to remove oxygen from oxygen-containing gases (oxygen scavenger) |
Manufacturing Quality Control of Gallic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Assay | High-Performance Liquid Chromatography (HPLC) | Utilizes a C18 reversed-phase chromatographic column with a mobile phase of methanol-water or acetonitrile-water containing acid (e.g., phosphoric acid or formic acid), employing gradient or isocratic elution. Detection is performed using a UV detector at approximately 270 nm to quantitatively analyze gallic acid content, offering high sensitivity and resolution. |
| Purity Check | High-Performance Liquid Chromatography (HPLC) | Analyzes the number and size of impurity peaks in the HPLC chromatogram to calculate total impurity content and evaluate sample purity. |
| Identification | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Gallic acid exhibits a characteristic absorption peak near 270 nm; identification is performed by comparing the UV spectrum of the test sample with that of a reference standard. |
| Identification | Thin-Layer Chromatography (TLC) | Uses a silica gel plate with an appropriate mobile phase (e.g., ethyl acetate-formic acid-water) for development. After visualization, the spot position (Rf value) is compared with that of a reference standard. |
| Water Content Determination | Karl Fischer Titration | Relies on the quantitative reaction between iodine and sulfur dioxide in an anhydrous environment with water to precisely determine the moisture content of the sample. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Oven Drying Method | The sample is dried at a specified temperature (e.g., 105°C) until constant weight is achieved; the loss in weight is used to calculate the total content of moisture and volatile components. |
| Residue on Ignition | Residue on Ignition Test | The weight of non-volatile inorganic residues remaining after high-temperature ignition of the sample, used to control limits of inorganic impurities. |
| Heavy Metals | Thioacetamide Method (Pharmacopoeia Method) | Under weakly acidic conditions, heavy metal ions react with thioacetamide to form colored sulfides; the total heavy metal content is determined by colorimetry. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | HPLC is used to detect structural analogs or degradation products of gallic acid (e.g., ellagic acid, protocatechuic acid) to assess impurity levels. |
| Microbial Limits | Microbial Limit Test | Performs aerobic microbial count, mold and yeast enumeration, and control organism testing (e.g., Escherichia coli) according to pharmacopoeial requirements. |
