CHLOROPHENOLRED-BETA-D-GALACTOPYRANOSIDE, SODIUM SALT

Description:
Chlorophenolred-beta-D-galactopyranoside, sodium salt, 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 presence of the beta-D-galactopyranoside structure allows it to be specifically cleaved by β-galactosidase, resulting in a measurable color change that can be quantified spectrophotometrically. As a sodium salt, it is typically soluble in water, facilitating its use in various laboratory applications. The compound is generally stable under standard laboratory conditions but should be stored properly to maintain its integrity. Safety data sheets recommend handling it with care, as with many chemical substances, to avoid potential hazards. Overall, chlorophenolred-beta-D-galactopyranoside serves as an important tool in molecular biology and microbiology for studying enzyme activity and gene expression.
