Used in medicinal chemistry as a key intermediate in the synthesis of potential anticancer agents, particularly histone deacetylase (HDAC) inhibitors. Its structure supports binding to the active site of HDAC enzymes, making it valuable in developing targeted therapies for various cancers. Also explored in research for treating neurodegenerative diseases due to its ability to modulate gene expression. Commonly employed in structure-activity relationship (SAR) studies to optimize potency and selectivity of drug candidates.
