Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinamide adenine dinucleotide (NAD) analogs and other biologically active compounds. Its nitrile groups allow for versatile functionalization, making it valuable in medicinal chemistry for developing enzyme inhibitors and receptor modulators. Also employed in the preparation of agrochemicals and functional materials due to its stable heterocyclic structure and ability to undergo selective transformations.
