Ethyl cyanoacetate

CAS: 105-56-6

Overview

Ethyl cyanoacetate (CAS 105-56-6 ), also known as cyanoacetic acid ethyl ester, is a reactive ester used as both a synthetic intermediate and a flavoring agent across chemical and consumer product industries.

Its dual role as a building block and flavor compound makes it relevant to procurement across multiple supply chains. In flavor and fragrance manufacturing, it contributes fruity, wine-like notes to finished flavor compositions.

Formulators in personal care rely on it as a reactive intermediate in the synthesis of active ingredients and specialty esters used in cosmetic formulations. As a monomer and building block, it is a key starting material.

It is used in the production of cyanoacrylate adhesives, pharmaceuticals, and agrochemical intermediates. These are applications where consistent purity directly affects downstream reaction yields and final product quality.

It also serves in the synthesis of heterocyclic compounds, including pyridines and pyrimidines, relevant to fine chemical and API manufacturing. This versatility makes it a staple in modern chemical synthesis.

The product is supplied as a clear liquid in standard drum and IBC quantities suited to industrial procurement volumes. Technical grade is the most common commercial form for general industrial use.

High-purity grades are available for flavor and pharmaceutical synthesis applications. Buyers should confirm purity specifications and packaging options with suppliers based on specific end-use requirements.
