  • Applications

    Tiglic acid aldehyde is a reactive alpha,beta-unsaturated aldehyde that can serve as a building block in organic synthesis. In practice, it is commonly evaluated for use as a fragrance ingredient or odorant in perfumery, as a precursor for aroma compounds in flavor chemistry, and as a building block for specialty polymers and plastics. It may also find use in coatings and inks as a reactive intermediate, and in cosmetics/personal care formulations as a fragrance additive, subject to local regulations and formulation limits.
