Manufacturing Quality Control of Ethylenediaminetetraacetic acid tetrasodium salt dihydrate
| Test Item | Common Test Method | Method Summary |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with the reference spectrum to confirm the presence of characteristic functional groups of tetrasodium edetate dihydrate (e.g., carboxylate, amino groups). |
| Sodium Ion Flame Test | Burn the sample in a colorless flame and observe whether a yellow flame is produced, providing preliminary confirmation of sodium ion presence. | |
| Assay | Complexometric Titration (Back-titration with EDTA) | Utilize the ability of EDTA anion to form stable complexes with metal ions (e.g., Zn²⁺, Ca²⁺). Add excess standardized metal ion solution, then back-titrate the unreacted metal ions with standardized EDTA solution to calculate the EDTA content in the sample. |
| High-Performance Liquid Chromatography (HPLC) | Use reversed-phase or ion-exchange chromatographic column to separate sample components with appropriate mobile phase. Quantify the main component using UV or refractive index detection; suitable for analysis of high-purity samples. | |
| pH Value | pH Meter Method | Prepare an aqueous solution of defined concentration (e.g., 1% w/v), and measure pH at specified temperature using a calibrated pH meter. The result should comply with pharmacopoeial or standard specifications (typically pH 10.5–12.0). |
| Loss on Drying | Thermogravimetric Analysis or Ordinary Drying Method | Dry the sample at 105°C to constant weight and determine the percentage weight loss, used to control the content of crystalline water and volatile impurities. Typically limited to ≤15.0% (theoretical weight loss for dihydrate is ~12.9%). |
| Sulfated Ash / Residue on Ignition | Residue on Ignition Test | Ignite the sample at high temperature (700–800°C), then weigh the residual inorganic matter to estimate total inorganic impurities. General limit is ≤0.1%. |
| Heavy Metals | Thioacetamide Method (Colorimetric) | In weakly acidic conditions, react sample solution with thioacetamide to form colored sulfide precipitates. Compare with lead standard solution to control heavy metal content (as Pb), typically ≤10 ppm. |
| Chlorides | Silver Nitrate Turbidimetry | Acidify sample solution with nitric acid, then add silver nitrate to generate white turbidity from chloride ions. Compare with standard sodium chloride solution to control chloride impurity, typically limited to ≤0.01%. |
| Sulfates | Barium Chloride Turbidimetry | Add barium chloride in hydrochloric acid medium to produce white barium sulfate turbidity from sulfate ions. Compare with standard potassium sulfate solution to control sulfate impurity, typically limited to ≤0.02%. |
| Water-Insoluble Matter | Filtration-Drying-Weighing Method | Dissolve sample in water, filter the insoluble residue, dry and weigh it to evaluate insoluble impurities. Generally required to be "practically clear" or insoluble matter ≤0.1%. |
