Tiglic acid is primarily used in the synthesis of complex organic molecules, especially in the fragrance and flavor industry. It serves as a building block for the preparation of various esters that exhibit fruity or floral aromas, making it valuable in perfumery. These esters are commonly found in artificial flavors and scented consumer products. It is also employed in pharmaceutical research as a chiral synthon, aiding in the development of bioactive compounds. Due to its reactive carboxylic acid group and defined stereochemistry, tiglic acid participates in coupling reactions and is used in the production of certain anti-inflammatory and antimicrobial agents. In addition, tiglic acid derivatives have been investigated for their potential in agrochemical applications, such as in the design of pesticides or growth regulators, where structural specificity influences biological activity.
