Product Overview
Trans-2-undecenal (CAS 53448-07-0, FEMA 3423), also named (E)-2-Undecenal, is an aliphatic unsaturated aldehyde. It carries characteristic fresh coriander, citrus peel and waxy herbal aroma. This natural-occurring flavor monomer appears in coriander leaves and some roasted food systems. Flavor houses rely on it to build authentic cilantro profiles and boost bright citrus top notes. It also works well in fine fragrance creation to add fresh, diffusive lift for cosmetic and home care scents.
