Definition
An indolyl carbohydrate that is the beta-D-galactoside 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-galactosidase, which cleaved the glycosidic bond to give 5-bromo-4-chloro-3-hydroxy-1H-indole, which immediately dimerises to give an intensely blue product.
