Used primarily in organic synthesis as a derivatizing agent for the detection and quantification of reactive sulfur species. It selectively reacts with hydrogen sulfide and other low-molecular-weight thiols, forming stable adducts that can be easily analyzed by HPLC or mass spectrometry. This makes it valuable in biochemical and pharmaceutical research for studying sulfur metabolism and redox processes in biological systems. Also employed in the development of sensors and assays for monitoring sulfide levels in environmental and clinical samples.
