Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. It serves as a building block in the preparation of hydrazine-containing heterocycles, which are important in medicinal chemistry for their bioactivity. Its sulfone and hydrazine functional groups allow for diverse chemical transformations, making it valuable in research settings for creating novel drug candidates. Also employed in the study of enzyme inhibitors due to its ability to mimic certain biological amine structures.
