Specifications | MSDS | Literature and Reviews

2-Fluoro-5-nitrobenzoic acid (CAS number 7304-32-7) is a benzoic acid derivative with substituents of a fluorine and a nitro-group at 2- and 5-positions. Fluorescent probes for detecting nucleophiles such as endogenous hydrogen polysulfide and hydrazine can be synthesised from 2-fluoro-5-nitrobenzoic acid and fluorescent dyes through esterification. The fluorescent probes have intrinsically weak fluorescence, and yet to be turned on by the targeting nucleophiles. The nucleophiles hydrolyse the fluorescent probes (ester hydrolysis), which releases the strong fluorescent dyes observed by fluorescent microscopy.

The fluorine atom substitutes beside the carboxylic group in 2-fluoro-5-nitrobenzoic acid, enabling it to synthesize polycyclic heterocycles and β-turn cyclic peptidomimetics.
