Phenolphthalein beta-D-Glucuronide (hydrate)

Phenolphthalein beta-D-glucuronide is a colorimetric substrate for beta-glucuronidase. Upon enzymatic cleavage by beta-glucuronidase, phenolphthalein is released, which can be quantified by colorimetric detection at 552 nm as a measure of beta-galactosidase activity.Formal Name: 4-[1,3-dihydro-1-(4-hydroxyphenyl)-3-oxo-1-isobenzofuranyl]phenyl, beta-D-glucopyranosiduronic acid, hydrate.
