Industrial Applications of Resazurin sodium salt
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Cell viability assay | Used to assess cell proliferation and cytotoxicity, with viable cell count indicated by color change resulting from a reduction reaction |
| Microbiology | Indicator for anaerobic bacterial culture | Added to growth media as a redox indicator to monitor anaerobic conditions in the culture environment |
| Biotechnology | Reactive oxygen species (ROS) detection | Employed as a fluorescent probe in ROS quantification assays to reflect intracellular oxidative stress levels |
| Environmental monitoring | Microbial metabolic activity analysis | Applied for rapid assessment of microbial community metabolic activity in water or soil samples |
| Food science | Detection of spoilage microorganisms in food | Used to evaluate microbial contamination levels in food via reduction-based colorimetric detection; applied in food preservation research |
Manufacturing Quality Control of Resazurin sodium salt
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state under natural light or standard illumination; Azure A should appear as deep blue to bluish-black crystalline powder. |
| Identification | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Determine the maximum absorption peak at a specific wavelength (e.g., around 600 nm) and compare with reference standard spectrum for identification. |
| Thin Layer Chromatography (TLC) | Develop on silica gel plates, visualize after staining, and compare Rf values and spot colors with reference standards to confirm compound consistency. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with appropriate mobile phase (e.g., methanol-water or acetonitrile-buffer salt system), employing isocratic or gradient elution, and UV detection (around 600 nm) for quantitative analysis of the main component. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Drying Loss Method | Dry the sample to constant weight at a specified temperature (e.g., 105°C), then calculate the percentage of mass loss to assess moisture and volatile content. |
| Residue on Ignition | Ignition Residue Method | Ignite the sample at high temperature (approximately 600–800°C), cool, and weigh the residual inorganic matter to control inorganic impurities. |
| pH Value | pH Meter Measurement | Prepare a solution of specified concentration (e.g., 1%), then measure pH using a calibrated pH meter. The typical range is close to neutral. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use chromatographic conditions similar to or optimized from those used for content determination to separate and detect potential degradation products or synthetic by-products. Impurity levels are calculated using area normalization or correction factors. |
| Solubility | Solubility Test | Observe solubility in solvents such as water, ethanol, DMSO, etc., to verify compliance with pharmacopeial or standard requirements. |
| Specific Rotation (if applicable) | Polarimeter Method | If Azure A exhibits optical activity (though typically it shows negligible optical rotation), specific rotation may be measured as an auxiliary identification parameter. |
