描述
Tiglic aldehyde, also known as 2-methyl-2-butenal, is a member of the class of compounds known as enals. Enals are an alpha,beta-unsaturated aldehyde of general formula RC=C-CH=O in which the aldehydic C=O function is conjugated to a C=C triple bond at the alpha,beta position. Tiglic aldehyde is soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Tiglic aldehyde is a strong, fruit, and green tasting compound and can be found in a number of food items such as safflower, garden tomato, herbs and spices, and spearmint, which makes tiglic aldehyde a potential biomarker for the consumption of these food products. Tiglic aldehyde can be found primarily in feces and saliva. Tiglic aldehyde is an organic compound with the formula CH3CH=C(CH3)CHO. This colorless liquid is a building block in organic synthesis. It is an α,β-unsaturated aldehyde related to the better-known crotonaldehyde. The European rabbit, Oryctolagus cuniculus, uses 2-methyl-2-butenal as a pheromone. The rabbit pheromone, trans-2-methyl-2-butenal, was reported to be involved in the communication between species, defined under the class of "interomone." .
