Manufacturing Quality Control of AZOMETHIN-H MONOSODIUM SALT HYDRATE
| 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 foreign particles under natural light or standard illumination. Formaldehyde sulfoxylate monosodium salt hydrate is typically a white to off-white crystalline powder. |
| Identification | Infrared Spectroscopy (IR) | Record the infrared absorption spectrum of the sample using an IR spectrometer and compare it with the reference spectrum to confirm the presence of characteristic functional groups (e.g., C=N, N–H, O–H), thereby verifying the compound's structure. |
| Identification | Proton Nuclear Magnetic Resonance (¹H NMR) | Dissolve the sample in a suitable deuterated solvent and analyze using ¹H NMR to determine chemical shifts, integration areas, and coupling constants of hydrogen atoms. Compare the resulting spectrum with a reference spectrum for structural confirmation. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a mobile phase such as phosphate buffer-acetonitrile. Detect with a UV detector (typically at 254 nm or at the compound’s maximum absorbance wavelength) and quantify the main component using an external standard method. |
| Water Content | Karl Fischer Titration | Quantify water content by reacting the sample with Karl Fischer reagent, which reacts stoichiometrically with water. Determine moisture content via volumetric or coulometric titration; suitable for precise control of water, including crystalline water, in compounds. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Constant Temperature Drying | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, then calculate the percentage weight loss. Used to assess total volatile content, including partial crystalline water. |
| Sulfated Ash / Residue on Ignition | High-Temperature Ignition | Ignite the sample at high temperature (typically 700–800°C) to ash, then weigh the residual inorganic material to evaluate levels of inorganic impurities or metal salt residues. |
| pH Value | pH Meter Method | Prepare an aqueous solution of defined concentration (e.g., 1% w/v) and measure its pH using a calibrated pH meter. The aqueous solution of formaldehyde sulfoxylate monosodium salt hydrate is typically weakly alkaline. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, determine the levels of heavy metals such as lead, cadmium, mercury, and arsenic using AAS or ICP-MS to ensure compliance with pharmacopoeial or regulatory limits. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use gradient or isocratic HPLC to separate and detect potential impurities such as synthesis by-products or degradation products. Quantify impurities using area normalization or a standard self-control method. |
