Description

3-Chlorocarbonylacrylic Acid Ethyl Ester is a versatile and reactive bifunctional intermediate, combining an acid chloride and an acrylate ester moiety within a single molecule. This unique structure makes it a critical building block for synthesizing complex organic compounds, particularly in the pharmaceutical and agrochemical sectors. It is essential for researchers and manufacturers developing active pharmaceutical ingredients (APIs), specialty chemicals, and advanced materials who require a reliable, high-purity source for their synthetic pathways.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of various heterocyclic compounds and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators.
• Polymer Chemistry: Serves as a monomer or cross-linking agent for specialty polymers and coatings.
• Organic Synthesis: A versatile reagent for Michael addition reactions, cyclizations, and the introduction of the acryloyl chloride functional group.
• Dye and Pigment Manufacturing: Intermediate in the synthesis of complex organic colorants.
• Research & Development: Valuable tool in medicinal chemistry and material science research for creating novel molecular architectures.

Quality Control

Our 3-Chlorocarbonylacrylic Acid Ethyl Ester is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and degradation. Keep away from heat, sparks, and open flame.
