Manufacturing Quality Control of Disodium phenyl phosphate dihydrate
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Compare sample spectrum with standard reference spectra to confirm consistency of molecular structural characteristic absorption peaks, used for qualitative identification. |
| Proton Nuclear Magnetic Resonance (¹H-NMR) | Analyze chemical shifts and coupling splitting patterns of hydrogen atoms to verify the correctness of molecular structure. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use reversed-phase chromatographic columns with UV detection; quantify main component content via external or internal standard method. Offers high accuracy and strong specificity. |
| Acid-Base Titration | Utilize the acidity of phosphate ester groups by titrating with standardized alkaline solution to calculate active ingredient content; suitable for rapid determination of relatively pure samples. | |
| Moisture | Karl Fischer Titration | Quantitatively determine water content based on iodine-sulfur dioxide reaction; particularly suitable for precise moisture analysis of compounds containing crystalline water. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Check for possible degradation products or synthetic intermediates as organic impurities, assessing purity and stability. |
| Solution Clarity and Color | Visual Colorimetry / UV-Visible Spectrophotometry | Prepare a solution at a specified concentration and visually assess clarity and color; quantitative absorbance may also be determined using spectrophotometry. |
| pH Value | pH Meter Measurement | Dissolve sample in water and measure pH using a calibrated pH meter to determine whether acidity or alkalinity meets pharmacopoeial requirements. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, detect residual levels of heavy metals such as lead, arsenic, cadmium, and mercury to ensure compliance with safety standards for pharmaceuticals or food additives. |
| Sulfate/Chloride | Ion Chromatography or Turbidimetry | Detect inorganic anion impurities (e.g., Cl⁻, SO₄²⁻) through standard calibration curves or visual turbidity comparison to determine if limits are exceeded. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Oven Method | Heat sample under specified conditions to constant weight and calculate percentage loss, evaluating content of crystalline water and volatile impurities. |
| Residue on Ignition | Ignition Test (Sulfated Ash) | Ignite sample at high temperature and treat with sulfuric acid; weigh residue to assess total inorganic impurity content. |
