Description

Methyl 2-Chloro-2-Propenoate is a highly reactive, halogenated acrylate ester monomer. This compound is valued for its ability to introduce both a polymerizable double bond and a reactive chlorine functionality into polymer chains, enabling the synthesis of specialty materials with tailored properties. It is a critical intermediate for manufacturers in the polymer, coatings, and specialty chemical industries seeking to develop advanced resins, adhesives, and functional materials.

Application

• Reactive Monomer for Specialty Polymers: Used in the synthesis of acrylic and methacrylic copolymers for high-performance coatings, adhesives, and sealants.
• Chemical Intermediate: Serves as a key building block in organic synthesis for pharmaceuticals and agrochemicals, where the chloro and ester groups offer versatile reaction sites.
• UV-Curable Resins & Inks: Incorporated into formulations for fast-curing, durable inks and coatings used in printing and electronics.
• Crosslinking Agent: Functions as a reactive crosslinker to enhance the thermal stability, chemical resistance, and mechanical strength of polymer networks.
• Surface Modifier: Used to graft functional groups onto polymer or material surfaces to alter wettability, adhesion, or biocompatibility.
• Research & Development: Employed in academic and industrial R&D labs for developing novel polymeric materials and studying polymerization mechanisms.

Quality Control

Our Methyl 2-Chloro-2-Propenoate is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications for industrial and research applications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature is 2-8°C (refrigerated) for extended stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
