Pyrenebutyric acid,芘丁酸,3443-45-6 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.
