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 ability to form stable heterocyclic structures that interact with biological targets. Commonly employed in the preparation of compounds with anti-inflammatory, antiviral, and anticancer activities. Its carboxylic acid functionality allows for easy derivatization, enabling the formation of amides and esters to optimize drug potency and pharmacokinetic properties. Also utilized in agrochemical research for designing novel pesticides and herbicides owing to its structural specificity and reactivity.
