Used in the synthesis of pharmaceuticals and agrochemicals due to its triazole ring, which contributes to biological activity. Acts as a building block in click chemistry, especially in the development of drug candidates and functional materials. Its carboxylic acid group allows for easy conjugation with other molecules, making it valuable in medicinal chemistry for creating libraries of compounds. Also employed in the preparation of fluorescent probes and sensors, where the triazole moiety enhances photostability and binding selectivity.
