Description

3-Cyanopropanoic Acid Ethyl Ester is a versatile bifunctional ester and nitrile compound that serves as a critical building block in organic synthesis. Its molecular structure, featuring both an ester and a cyano group, makes it a valuable precursor for constructing complex molecules, particularly in the pharmaceutical and agrochemical sectors. This high-purity intermediate is essential for research and production chemists developing active pharmaceutical ingredients (APIs), fine chemicals, and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of various heterocyclic compounds, GABA analogs, and other active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators requiring specific nitrile and ester functionalities.
• Fine Chemical Production: Serves as a precursor for dyes, pigments, and specialty polymers where its reactive groups allow for further functionalization.
• Organic Synthesis Reagent: Employed in Michael addition reactions, cyclization processes, and as a starting material for preparing amino acids and their derivatives.
• Material Science Research: Utilized in the development of novel monomers for specialty polymers and advanced functional materials.

Quality Control

Our 3-Cyanopropanoic Acid Ethyl Ester is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC, GC) and spectroscopy (IR, NMR), to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP requirements for pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. The container should be kept tightly closed in a dry and well-ventilated place. Containers that have been opened must be resealed carefully and held upright to prevent leakage.
