Manufacturing Quality Control of bis(5-oxo-L-prolinato-N1,O2)zinc
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, physical state, and presence of caking in the sample under natural or standard lighting to determine if the appearance meets specifications. |
| Identification Test | Infrared Spectrophotometry (IR) | Compare the infrared spectrum of the sample with that of a reference standard; confirm consistency of characteristic absorption peaks to verify chemical structure. |
| Ultraviolet-Visible Spectrophotometry (UV-Vis) | Measure absorbance characteristics of the sample at specific wavelengths to assist in identifying characteristic absorption peaks of zinc pyrrolidone carboxylate. | |
| Assay (Zinc Content) | Atomic Absorption Spectrophotometry (AAS) | Determine zinc content using an atomic absorption spectrometer; provides accurate quantification with high specificity. |
| Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | High-sensitivity determination of zinc and other metal impurities; suitable for simultaneous multi-element analysis with high precision. | |
| Assay (Organic Component) | High-Performance Liquid Chromatography (HPLC) | Separate and quantify the pyroglutamic acid component using a reversed-phase column and UV detection; calculate the main component content. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at a specified temperature (e.g., 105°C) to constant weight; calculate moisture and volatile content based on weight loss. |
| Sulfated Ash / Residue on Ignition | Sulfated Residue Method | Ignite the sample at high temperature, treat with sulfuric acid, and weigh the residue to assess inorganic impurity content. |
| Heavy Metals Limit Test | Sulfide Colorimetry (Chinese Pharmacopoeia Method) | In acidic conditions, react with hydrogen sulfide to form colored precipitates; use colorimetry to determine total heavy metals (expressed as lead). |
| ICP-MS | Highly sensitive detection of specific heavy metal elements such as lead, cadmium, mercury, and arsenic; complies with international pharmacopoeial requirements. | |
| pH Value | pH Meter Method | Prepare an aqueous solution of specified concentration from the sample and measure its pH using a calibrated pH meter to determine whether it falls within the acceptable range. |
| Microbial Limits | Microbial Limit Test (Plate Count Method) | Perform testing according to the *Chinese Pharmacopoeia* or relevant standards, including total aerobic microbial count, mold and yeast count, and tests for specified microorganisms (e.g., *E. coli*). |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Determine particle size distribution based on laser scattering principles to evaluate uniformity and dissolution performance. |
| Solubility | Solubility Test | Add the sample to solvents such as water or ethanol, shake well, and observe solubility to determine compliance with specified solubility characteristics. |
