Ethyl Vanillin CAS 121-32-4 is a synthetic aromatic flavor compound designed to mimic and enhance the characteristic vanilla aroma and taste. Compared with vanillin, ethyl vanillin features an ethoxy group on the benzene ring, which gives it a more potent and long-lasting vanilla profile in sensory applications.
