Oleoyl chloride is widely used in organic synthesis, particularly in the production of esters and amides. It serves as a key reagent in the acylation of alcohols and amines, enabling the formation of oleic acid derivatives. In the pharmaceutical industry, it is employed to modify drug molecules, enhancing their solubility or bioavailability. Additionally, it is utilized in the manufacturing of surfactants and emulsifiers, which are essential in cosmetics and personal care products. In polymer chemistry, oleoyl chloride is used to create specialized polymers with tailored properties, such as flexibility or hydrophobicity. Its reactivity with cellulose and other natural fibers makes it valuable in the textile industry for fabric treatment and modification.
