Carminic Acid Analytical Grade

The Carminic Acid Analytical Grade by Dinâmica, available at LojaLab, is a natural anthraquinone glycoside dye identified by CAS 1260-17-9 and Colour Index Natural Red 4. The molecule contains an anthraquinone chromophore linked to a sugar unit, producing intense red coloration and spectral behavior that depends on pH, solvent and the presence of metal ions. In solution, changes in protonation and complexation may alter hue, intensity and the wavelength of maximum absorption. The reagent may be used in natural-pigment research, colorimetry, spectrophotometry, complexation studies and method development.
