Manufacturing Quality Control of Methylene Blue trihydrate
| Test Item | Common Testing Methods | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and physical state of the sample. Qualified methylene blue should appear as dark blue lustrous crystals or powder, free from visible impurities. |
| Identification | UV-Visible Spectrophotometry (UV-Vis) | Identification based on the characteristic absorption peak of methylene blue at a specific wavelength (e.g., around 664 nm). |
| Assay | Spectrophotometry / Titration | Spectrophotometry: Determine concentration by measuring absorbance at the maximum absorption wavelength according to the Lambert-Beer law. Titration: Redox titration (e.g., reaction with ascorbic acid or indirect determination via iodometric method). |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use reversed-phase HPLC to separate the main component from impurities (such as intermediates or degradation products); impurity levels are evaluated using reference standards or area normalization methods. |
| Loss on Drying | Thermogravimetric Analysis (or Oven Method) | Dry the sample at 105°C to constant weight; calculate the content of moisture and volatile substances based on weight loss. |
| Sulfated Ash (Residue on Ignition) | Gravimetric Method | After high-temperature incineration of the sample, the residue is treated with sulfuric acid and weighed to assess inorganic impurity content. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine the content of heavy metal elements such as lead, mercury, and cadmium using AAS or inductively coupled plasma mass spectrometry (ICP-MS). |
| pH Value | pH Meter Method | Prepare an aqueous solution of specified concentration (e.g., 0.1%), then measure acidity or alkalinity using a calibrated pH meter. |
| Solubility | Solubility Test | Observe the solubility of methylene blue in solvents such as water, ethanol, and chloroform, confirming compliance with pharmacopoeial requirements. |
| Microbial Limits | Microbial Limit Test | Perform tests according to pharmacopoeial requirements, including total aerobic microbial count, mold and yeast count, and testing for specified microorganisms (e.g., Escherichia coli). |
