Synonyms:	(-)-5-bromo-4-chloro-3-indolyl-beta-D-glucoside, 5-bromo-4-chloro-1H-indol-3-yl beta-D-glucopyranoside, 5-bromo-4-chloro-3-indolyl beta-glucoside, 5-bromo-4-chloroindol-3-yl-beta-D-glucopyranoside, EINECS 239-603-0, Indoxyl-Glucoside, X-Glc, X-glucoside
Definition:	An indolyl carbohydrate that is the beta-D-glucoside of 3-hydroxy-1H-indole in which the indole moiety is substituted at positions 4 and 5 by chlorine and bromine, respectively. It is used to test for the presence of an enzyme, beta-glucosidase, which cleaves the glycosidic bond to give 5-bromo-4-chloro-3-hydroxy-1H-indole, which immediately dimerises to give an intensely blue product.
