Bromocresol green
pH Indicator
Bromocresol green is a pH-sensitive triphenylmethane dye primarily utilized as a pH indicator. It exhibits a color change from yellow in acidic conditions (pH = 4.15) to blue in basic environments, with maximum absorption at 435 nm and 615 nm, respectively. This dye is extensively applied in biochemical analysis for determining protein and albumin concentrations in serum, as well as assessing creatinine levels and evaluating cell viability. Its reliable colorimetric properties make it a valuable tool in various research and clinical settings.
