Butyl crotonate is widely used in the production of polymers and resins, where it acts as a key monomer. Its application in the synthesis of copolymers enhances properties such as flexibility and durability, making it valuable in the manufacture of coatings, adhesives, and sealants. Additionally, it serves as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. In the flavor and fragrance industry, butyl crotonate is utilized for its fruity aroma, contributing to the formulation of perfumes and food flavorings. Its solvent properties also make it useful in industrial cleaning applications and as a reaction medium in various chemical processes.
