6-Chloro-3-indolyl butyrate , Salmon-butyrate

6-Chloro-3-indolyl butyrate is an enzyme substrate that is used in a variety of applications, including environmental testing and diagnostics. 6CIBA is a fluorogenic substrate that can be used to detect the presence of peroxidase or other oxidizing enzymes in a variety of different samples, such as culture media, food testing, and diagnostics. 6CIBA reacts with hydrogen peroxide or other oxidant to produce 6-chloro-3-indolyl acetic acid (6CIAA), which has a high extinction coefficient at 350 nm and can be detected using a fluorescence spectrophotometer.
