5-Bromo-4-chloro-3-indolyl nonanoate, X-Nonanoate

5-Bromo-4-chloro-3-indolyl nonanoate is a fluorogenic substrate that is used in the detection of enzymes. The substrate reacts with various enzymes and produces a fluorescent product, which can be detected using a fluorimeter or luminometer. It has been shown to be active against β-galactosidase, α-chymotrypsin, and β-glucuronidase. This compound may also be used as an enzyme substrate for the detection of bacteria in culture media or for food testing. 5-Bromo-4-chloro-3 indolyl nonanoate is not mutagenic or genotoxic when tested on bacterial cells.
