6-Chloro-3-indoxyl-3-acetate

6-Chloro-3-indoxyl-3-acetate is a fluorogenic substrate used in food testing and environmental testing. It is also a chromogenic substrate that can be conjugated to an enzyme or ligand for use in diagnostics. 6-Chloro-3-indoxyl-3-acetate has high purity and quality, and is CAS No. 114305-99-6. It reacts with hydrogen peroxide to form 6-(chloromethyl) indole, which generates light when oxidized by the horseradish peroxidase enzyme. This reaction is called chemiluminescence or bioluminescence, depending on the type of reaction being catalyzed by the horseradish peroxidase enzyme.
