Used as a building block in the synthesis of pharmaceuticals and agrochemicals due to its nitrogen-rich heterocyclic structure. Its carboxylic acid groups allow for easy derivatization, making it valuable in creating active ingredients in crop protection agents and medicinal compounds. It also serves in coordination chemistry as a ligand for metal ions, useful in catalysis and material science. Research explores its potential in developing new bioactive molecules with antimicrobial or anti-inflammatory properties.
