Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical and agrochemical industries. It serves as an alkylating agent due to the reactive chloromethyl group, enabling the introduction of ester functionalities into target molecules. Its structure allows for further functionalization, making it valuable in the preparation of active ingredients in crop protection agents and certain drug compounds. The compound is also employed in the synthesis of specialty esters and fragrances where controlled reactivity is required. Handling requires caution due to its lachrymatory and moisture-sensitive properties.
