Application
Ethyl cinnamate is a widely used aroma chemical in the flavor and fragrance industry. It imparts sweet, fruity, and honey like notes to perfumes, soaps, and cosmetics, often used in oriental and floral compositions. As a flavoring agent, it enhances strawberry, cherry, plum, and cinnamon profiles in beverages, baked goods, and confectionery. In the polymer industry, ethyl cinnamate serves as a monomer in UV curable coatings and inks due to its reactive double bond, contributing to fast curing and good adhesion. It is also employed as a precursor for the synthesis of pharmaceutical intermediates, including certain antihypertensive and antidiabetic compounds. Additionally, it acts as a UV absorber in sunscreens and plastic additives, and as a starting material for cinnamic acid derivatives used in agrochemicals and preservatives. In academic research, it is a standard for photodimerization studies and as a model compound for transesterification reactions.
