Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its rigid heterocyclic structure, which enhances binding selectivity to biological targets. Commonly employed in the preparation of compounds with anti-inflammatory, antiviral, and central nervous system activity. Its carboxylic acid functionality allows for easy derivatization, enabling the formation of amides and esters to optimize drug potency and pharmacokinetic properties.
