CAS:Tartrazine is a yellow synthetic food dye that has been used since the late 1800s. It is classified as a non-steroidal anti-inflammatory drug (NSAID). Tartrazine binds to the response element on DNA, which inhibits gene transcription and causes cell death. The rate constant for this reaction was determined using crystalline cellulose as the substrate. Mouse monoclonal antibodies were used to measure the rate constant of transfer reactions between tartrazine and optical sensor. The optimum concentration for tartrazine was determined using toxicity studies in rats.Formula:C16H9N4Na3O9S2Purity:Min. 95%Color and Shape:PowderMolecular weight:534.37 g/molTartrazine solution

CAS:Applications As a dye for wool and silks; as colorant in food, drugs, and cosmetics. In biochemistry as an adsorption-elution indicator for chloride estimations. Tartrazine (otherwise known as E number E102, C.I. 19140, or FD&C Yellow 5) is a synthetic lemon yellow azo dye used as a food coloring. Tartrazine appears to cause the most allergic and intolerance reactions of all the azo dyes, particularly among asthmatics and those with an aspirin intolerance. Dyes and metabolites, Environmental Testing.A recent report has shown that Tartrazine may be useful in 3D bio-printing of organ-like architectures. References Rowe, K.S., et al.: J.
