Used primarily as an intermediate in organic synthesis, this compound is key in the production of peroxides such as di-2-ethylhexanoyl peroxide, which serves as a radical initiator in polymerization reactions. It is also employed in the synthesis of esters used as plasticizers, improving flexibility and durability in polymers like PVC. Its reactivity makes it valuable in forming amides and other acyl derivatives in pharmaceutical and agrochemical manufacturing. Due to its moisture sensitivity, it is handled under anhydrous conditions in industrial processes.
