Description and Uses

Pyrenylbutyric acid is a derivative of pyrene hydrocarbon with a free carboxylic acid function. The reagent is useful as a control for experiments with other reactive pyrene derivatives such as pyrene NHS ester and pyrene azide. Carboxylic acid function can be activated by carbodiimides and other activating reagents.

1-Pyrenebutyric Acid is a fluorescent probe used to study proteins, lipids, nucleic acids and other biological systems. The fluorescence lifetime of 1-Pyrenebutyric Acid depends on local oxygen and free radical concentration.
