ChEBI: 5-bromo-4-chloro-3-indolyl alpha-D-glucoside is an indolyl carbohydrate that is the alpha-D-glucoside of indoxyl in which the indole moiety is substituted at positions 4 and 5 by chlorine and bromine, respectively. It is an organobromine compound, an organochlorine compound, an indolyl carbohydrate, a D-aldohexose derivative and an alpha-D-glucoside. It is functionally related to an indoxyl.
5-Bromo-4-chloro-3-indolyl α-D-glucopyranoside, X-Gluc, is a indigogenic substrate for β- glucuronidase enzyme (GUS). It aids screening of transgenic plants based on GUS activity. GUS deesterifies X-Gluc into indoxyl derivative which upon oxidative polymerization results in the generation of blue indigotin dye.
