Butyl cinnamate

Butyl cinnamate (CAS 538-65-8, EC 208-699-6) is an ester of cinnamic acid and n-butanol, commercially referenced under names including N-Butyl Cinnamate and NSC 71966. It carries no assigned E-code and belongs to the flavors and fragrances chemical category with the molecular formula C13H16O2.

In personal care formulations, butyl cinnamate functions as a fragrance fixative, extending the longevity of scent profiles by slowing the evaporation of lighter aromatic compounds. In food and nutrition applications, it serves as a flavoring agent, contributing warm, balsamic, and cinnamon-adjacent notes to confectionery, beverages, and baked goods at controlled usage levels.

Butyl cinnamate is supplied in liquid form and falls under HS code 2916399000 for customs classification across EU trade. It is subject to REACH registration requirements for European market supply. Procurement teams should confirm FCC or food-grade certification depending on the intended application prior to ordering.
