1-(3-Ethylphenyl)ethan-1-one, also known as 3-Ethylacetophenone, a naturally occurring component found within Capsicum annuum plants, has demonstrated effectiveness as an insect repellent, particularly against insects like leaf-eating beetles, aphids, and thrips. It is synthesized from the esterification of acetophenone with ethanol and acetic acid. This compound can also be produced as an oxidation product of capsaicinoids like capsaicin and dihydrocapsaicin. Notably, it is used in magnetic resonance spectroscopy (MRS) experiments due to its elevated proton chemical shift and significant dipolar coupling constant, making it a valuable probe relative to other prevalent plant tissue compounds.
