Used in pharmaceutical research as a key intermediate in the synthesis of hydroxamic acid-based compounds, particularly in the development of histone deacetylase (HDAC) inhibitors. These inhibitors are studied for their potential in treating cancer and other diseases involving gene expression regulation. Also employed in the design of metalloenzyme inhibitors due to its ability to chelate metal ions in active enzyme sites. Its structure supports the development of bioactive molecules with improved binding affinity and selectivity.
