Manufacturing Quality Control of 139-89-9
| Test Item | Common Test Method | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Place an appropriate amount of sample on a white background and observe its color, physical state, and presence of impurities under natural light or standard illumination. It should appear as white to off-white crystalline powder. |
| Identification | Infrared Spectroscopy (IR) | Prepare a pellet of the sample and record its infrared absorption spectrum. Compare with the reference spectrum; major characteristic absorption peaks (e.g., carboxylate, amine functional groups) should match. |
| pH Value | Potentiometric Titration / pH Meter Method | Prepare an aqueous solution of defined concentration (e.g., 1% w/v), and measure pH using a calibrated pH meter. The pH typically should be within the range of 9.0–11.0. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Constant Weight Drying Method | Dry the sample at 105°C until constant weight is achieved. Calculate the percentage weight loss to assess moisture and volatile content; generally required to be ≤1.0%. |
| Sulfated Ash (Residue on Ignition) | High-Temperature Incineration Method | The sample is charred and then incinerated in a muffle furnace at 700–800°C until constant weight. The residual inorganic matter is weighed, and the residue percentage is calculated; typically limited to ≤0.1%. |
| Heavy Metals | Thioacetamide Method (Colorimetry) or Atomic Absorption Spectroscopy (AAS) | The sample is acid-digested, followed by color development using reagents such as thioacetamide for comparison, or analyzed by AAS to determine total heavy metals (e.g., Pb, Cd, Hg, As). Limit is generally ≤20 ppm. |
| Assay (Content Determination) | Complexometric Titration (EDTA Back Titration) | Exploit the sample's ability to form stable complexes with metal ions (e.g., Zn²⁺ or Cu²⁺). Add excess standard metal ion solution, then back-titrate the unreacted metal ions with standardized EDTA solution using Eriochrome Black T or PAN as indicator. Calculate active ingredient content, which typically should be ≥98.0%. |
| Chlorides | Silver Nitrate Turbidity Test | Acidify the sample solution with nitric acid, then add silver nitrate reagent. Compare turbidity with that of a standard sodium chloride solution to control chloride impurity levels; typically limited to ≤0.01%. |
| Sulfates | Barium Chloride Turbidity Test | Acidify the sample solution with hydrochloric acid, then add barium chloride reagent. Compare turbidity with that of a standard potassium sulfate solution to control sulfate impurity levels; typically limited to ≤0.02%. |
| Organic Impurities (Related Substances) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a mobile phase of phosphate buffer-methanol or acetonitrile. Detect using a UV detector (e.g., at 210 nm). Determine purity of the main peak and levels of individual impurities via area normalization or external standard method. Individual impurities typically ≤0.5%, total impurities ≤1.0%. |
