Carmoisine Red Extra Pure is a high-purity synthetic azo dye widely used in laboratory settings for analytical and diagnostic applications, especially in colorimetric assays, pH studies, and chromatographic analysis. Known for its vibrant red hue and excellent solubility in water, it provides consistent and stable coloration under controlled conditions. In biochemical and pharmaceutical research, it serves as a model compound for dye interaction studies and compound tracing. The extra pure grade ensures low levels of impurities, offering high reliability in sensitive experimental work. It should be handled with care, stored in a cool, dry area, and protected from light to maintain its structural and color integrity.
Carmoisine Red Extra Pure
Primary Uses
- Colorimetric Indicator in Analytical Chemistry
- Used in qualitative analysis and colorimetric methods to track reaction endpoints, especially in dye-sensitized tests or pH-related color changes.
- Spectrophotometric Calibration and Research
- Employed as a standard dye in UV-Vis spectrophotometry for studying absorption spectra, dye behavior, and solubility dynamics.
- Model Compound in Dye Degradation Studies
- Acts as a test pollutant in photocatalysis and wastewater treatment research, helping evaluate removal efficiency of dyes using various lab methods (e.g. TiO₂ photocatalysts, Fenton reaction).
- Chromatography Practice & Separation Studies
- Used in paper and thin-layer chromatography training and method development, due to its vivid color and predictable migration.
Secondary Uses
- Educational Demonstration of Food Dye Behavior
- Serves as a demo reagent in school and university labs to show solubility, diffusion, and dye interactions.
- Standard for Dye Stability Tests
- Applied in experiments to test thermal and light stability of synthetic azo dyes.
- Toxicology and Allergenicity Research Models
- Occasionally used as a representative synthetic dye in in vitro assays exploring allergenic or toxic dye effects.
