CAS 76-60-8: Bromocresol green

Description: Bromocresol green is a synthetic dye and pH indicator commonly used in various biochemical applications. It is characterized by its ability to change color in response to pH variations, typically transitioning from yellow in acidic conditions to blue in alkaline environments, with a pH transition range around 3.8 to 5.4. This property makes it valuable in titrations and as a biological stain. Chemically, bromocresol green is a sulfonated phenol derivative, and its molecular structure includes bromine atoms, which contribute to its colorimetric properties. It is soluble in water and exhibits a distinct absorption spectrum, making it useful in spectrophotometric analyses. Additionally, bromocresol green is often employed in microbiological and clinical laboratories for the detection of certain microorganisms and in the assessment of protein concentrations. While generally considered safe for laboratory use, it is important to handle it with care, as with all chemical substances, to avoid potential health hazards.
