Chlorophenol red §-D-galactopyranoside

Description:

Chlorophenol red β-D-galactopyranoside is a synthetic compound commonly used as a chromogenic substrate in biochemical assays, particularly for the detection of β-galactosidase activity. This compound features a chlorophenol red moiety, which provides a colorimetric change upon hydrolysis, making it useful for monitoring enzymatic reactions. The β-D-galactopyranoside part of the molecule indicates that it is a glycoside, specifically a galactose sugar linked to the chlorophenol red through a glycosidic bond. This structure allows the compound to be cleaved by β-galactosidase, releasing chlorophenol red, which changes color depending on the pH of the solution, typically shifting from yellow to red as the pH increases. The compound is soluble in water and is often employed in microbiological studies, molecular biology, and various laboratory applications to assess enzyme activity. Safety data should be consulted before handling, as with any chemical substance, to ensure proper precautions are taken.

Chlorophenol red b-D-galactopyranoside

CAS: 99792-79-7

Used in biological studies as a chromogenic substrate for β-galactosidase; red color.Chlorophenol red indicates changes of pH in the range of 4.8 to 6.7 by turning the solution from yellow (at pH 4.8) to violet (at pH 6.7). Converted as signalogenic moiety of an enzyme substrate, chlorophenol red beta-D-galactopyranoside has a good proven sensitivity in the detection of beta-galactosidase activity in transfected mammalian cells, when compared to ONPG (o-nitrophenyl-beta-D-galactopyranoside) (Eustice, 1991)
