Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its structure allows for functionalization in multi-step reactions, making it valuable in constructing complex molecules. The sulfinyl group can act as a directing group or chiral auxiliary in asymmetric synthesis, enabling selective formation of desired stereoisomers. Additionally, it has been explored in the preparation of biologically active compounds, including anti-inflammatory and enzyme inhibitory agents. Its carboxylic acid functionality facilitates derivatization into esters, amides, or salts for improved solubility or activity in final products.
