Used as a chromogenic substrate for N-Acetyl-β-D-galactosaminidase, yielding a blue precipitate. It is also used to detect Candida albicans.

5-Bromo-4-chloro-3-indoxyl-3-acetate is a histochemical substrate for esterase.

X-β-D-glucuronide sodium salt is a substrate for β-glucuronidase (GUS), yielding a blue precipitate upon cleavage. X-β-D-glucuronide sodium salt is highly accepted as an accurate test for the presence of E. coli in water. X-β-D-glucuronide sodium salt is nonelectrostatic and possesses a naturally occurring cation; therefore, it has advantages over X-β-D-glucuronide cyclohexylammonium salt.

5-Bromo-4-chloro-3-indoxyl-beta-D-mannopyranoside is a chromogenic substrate.

X-α-D-Glucoside is a white to off-white microcrystalline powder that is used as a chromogenic substrate for α-D-glucosidase, which yields a blue precipitate. It is used for the detection of Staphylococcus aureus and species within Bacilli. It is also used in the isolation of Enterobacter sakazakii.

A chromogenic substrate for β-D-Cellobiosidase, yielding a blue precipitate.

X-β-D-Xyloside is a white to off-white crystalline powder that is used as a chromogenic substrate for β-D-xylosidase, yielding a blue precipitate when cleaved.
