Used as a key intermediate in the synthesis of pharmaceutical compounds, 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 antitumor agents and anti-inflammatory drugs. Its carboxylic acid functionality allows for easy derivatization, enabling the formation of amides and esters to optimize drug potency and pharmacokinetics. Also utilized in research settings for designing novel bioactive molecules with potential therapeutic applications.
