The present invention relates to a coumarin derivative of Formula (L) for detection of cysteine and process for preparation thereof. The present invention further relates to a process of detection of cysteine residues present in protein as well as the cysteine released by the enzymatic action of aminoacylase 1 by using coumarin derivative of Formula (L).

A reaction-based colorimetric and ratiometric fluorescent probe based on an ICT-strategy for selective detection of H2S that exploited the H2S-mediated reduction of nitrocompound to amines was explored. And it displayed high selectivity for H2S over other relevant reactivesulfur, oxygen, nitrogenspecies and other anions with more than 120 nm blue shift and the change of emission intensity ratio inducted
