Quick Summary

Tiglic acid is an organic compound that is an unsaturated aliphatic acid. It is a cis-trans isomer, meaning it exists in two forms: angelic acid (the cis isomer) and tiglic acid (the trans isomer). Tiglic acid is found naturally in croton oil and other natural products. It is a liquid compound with the chemical formula C₄H₇CHO and has an odor similar to bitter almonds. Tiglic acid is also known as α-methyl-crotonaldehyde. Unsaturated acids, like tiglic acid, exhibit chemical properties associated with both a carboxyl group (COOH) and carbon-carbon double bonds.123
