Tiglic aldehyde

Basic Information

Product name: Tiglic aldehyde

Chinese name: tiglic 醛；反式-2-甲基-2-丁烯醛

Molecular Formula: C₅H₈O

Molecular weight: 84.12 g/mol

Structure: This is an α,β-unsaturated aldehyde with a branched carbon chain and a conjugated double bond adjacent to the carbonyl group. It is the trans-isomer of 2-methyl-2-butenal.

Tiglic aldehyde is a naturally occurring unsaturated aldehyde with a pungent, fruity odor. It appears as a colorless to pale yellow liquid and is used in various applications due to its reactivity and aroma. It is a structural isomer of angelic aldehyde (cis-2-methyl-2-butenal) and plays a role in both synthetic organic chemistry and the flavor and fragrance industry.

Main Uses

Flavor and Fragrance Industry

• Used as a flavoring agent and aroma compound in perfumes, food additives, and cosmetics due to its strong, fruity, and spicy odor.

Organic Synthesis Intermediate

• Serves as a reactive intermediate in the synthesis of pharmaceuticals, agrochemicals, and other fine chemicals, particularly in reactions involving the α,β-unsaturated aldehyde group.

Polymer and Resin Industry

• Can be used in the modification of resins and as a monomer or reactive additive in specialty polymers.

Typical Applications

Aldol Condensation

Participates in aldol-type reactions to form carbon–carbon bonds, often used in building more complex organic molecules.

Michael Addition

Acts as a Michael acceptor due to the conjugated double bond system, facilitating nucleophilic additions in organic synthesis.

Fragrance Formulations

Incorporated into formulations for spicy, fruity, or green notes in perfumes and flavorings.
