Used as a key intermediate in organic synthesis, particularly in the preparation of sulfonated compounds with potential biological activity. It serves in the development of fluorescent probes due to its conjugated aromatic system, enabling applications in imaging and sensor technologies. Also employed in the study of sulfonyl-based reactions for pharmaceutical research, where it helps model reaction pathways involving sulfonyl vinyl intermediates. Its rigid structure makes it useful in materials science for designing organic semiconductors and optoelectronic materials.
