Used primarily as an intermediate in organic synthesis, this compound is valuable in the preparation of esters and other acyl derivatives. Its reactivity makes it suitable for introducing acetoxypropionyl groups in pharmaceuticals and agrochemicals. It is also employed in the synthesis of chiral building blocks, useful in asymmetric synthesis. Due to the presence of the chloride group, it readily reacts with nucleophiles such as alcohols, amines, and thiols, enabling the formation of amides, esters, and thioesters under controlled conditions. Commonly handled under anhydrous and inert conditions due to moisture sensitivity.
