Description
Ethyl cyanoacetate (CAS 105-56-6), also known as ECYA, cyanoacetic ester, or ethyl cyanoethanoate, is a low-viscosity liquid organic compound carrying both a nitrile and an ester functional group. It carries no assigned E-code and is commercially identified under the EC number 203-309-0.
In food and beverage applications, ECYA functions as a flavoring intermediate, where its active methylene group undergoes condensation reactions to build aroma compounds with fruity or honey-like character. In personal care formulations, it serves as a reactive building block for synthesizing fragrance molecules, contributing to scent profiles through controlled chemical derivatization rather than direct odor deposition.
Ethyl cyanoacetate is supplied as a liquid in compliance with FCC (Food Chemicals Codex) grade specifications and falls under REACH registration requirements for EU market supply. It is classified under HS code 29269090 and is available in standard drum and IBC packaging formats suited to industrial procurement volumes.
