Bromophenol blue indicator (3.0-4.6) | Bromophenol blue indicator (3.0-4.6) is a synthetic dye commonly used as an acid-base indicator with a transition range of pH 3.0-4.6. Bromophenol blue indicator (3.0-4.6) is water soluble and changes color from yellow to blue as the pH of the solution changes from acidic to basic. Its unique chemical properties make it an important ingredient in a variety of scientific applications, especially in biochemistry and molecular biology. In addition, it can be used as a stain in microbiology and histology. However, Bromophenol blue indicator (3.0-4.6) has potential irritating and staining properties. | |||||||||||||||||||||

Bromocresol green | 99.59% | Bromocresol green is a pH-sensitive triphenylmethane dye commonly used for the determination of protein and albumin in serum. Bromocresol green is a bio-based dye with a yellow-green to blue-green color. Bromocresol green turns yellow (λmax=435 nm, protonated form) when placed in acidic solution (e.g. pH=4.15), and turns blue in basic solution (λmax=615 nm, deprotonated form). Bromocresol green is widely used as a pH indicator in the field of biochemical analysis. In addition, Bromocresol green is also used to detect the concentration of molecules such as creatinine, and to judge the viability of cells. | ||||||||||||||||||||
