Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of anti-inflammatory and analgesic agents. Its reactive chloroacetamido group allows for easy conjugation with other molecules, making it valuable in medicinal chemistry for building complex drug structures. Also employed in the preparation of labeled compounds for biochemical research, where it can be modified to track metabolic pathways or study protein interactions. Its carboxylic acid functionality enables esterification or amidation, facilitating incorporation into larger molecules with tailored biological activity.
