Common Name7-Acetoxy-7-methyl-3-methylene-1-octene
Description7-acetoxy-7-methyl-3-methylene-1-octene is a member of the class of compounds known as carboxylic acid esters. Carboxylic acid esters are carboxylic acid derivatives in which the carbon atom from the carbonyl group is attached to an alkyl or an aryl moiety through an oxygen atom (forming an ester group). 7-acetoxy-7-methyl-3-methylene-1-octene is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 7-acetoxy-7-methyl-3-methylene-1-octene is a bergamot, citrus, and floral tasting compound found in pot marjoram, which makes 7-acetoxy-7-methyl-3-methylene-1-octene a potential biomarker for the consumption of this food product.
