Bromocresol green

Description: Bromocresol Green, a triphenylmethane dye, serves primarily as a pH indicator transitioning from yellow (lambdamax=435 nm, protonated form) at pH 4.15 to blue (lambdamax=615 nm, deprotonated form) in alkaline environments. Utilized in biochemical analysis, it quantifies serum protein and albumin, assesses creatinine concentration, and evaluates cell viability [1] [2] [3] [4]. The dye exhibits a bio-based, yellow-green to blue-green hue. Smiles: O=S1(=O)OC(C=2C=CC=CC21)(C3=CC(Br)=C(O)C(Br)=C3C)C4=CC(Br)=C(O)C(Br)=C4C
