Ethyl 3-cyclobutylacrylate is primarily used in organic synthesis as a building block for more complex molecules. Its structure, featuring a cyclobutyl group and an acrylate moiety, makes it valuable in the development of polymers and fine chemicals. In polymer chemistry, it can be incorporated into copolymers to modify properties such as flexibility, adhesion, and thermal stability. Additionally, it serves as an intermediate in the synthesis of pharmaceuticals and agrochemicals, where the cyclobutyl ring can impart unique biological activity. Its reactivity in Michael addition and polymerization reactions makes it a versatile compound in research and industrial applications.
