Methacryloyl Chloride CAS 920-46-7
Aure Chemical Delivers Reliable Methacryloyl Chloride (CAS 920-46-7) at Consistent Quality
Methacryloyl chloride is a reactive liquid that features both an acid chloride functionality and a polymerizable methacrylic double bond. It readily participates in acylation reactions with nucleophiles and undergoes radical polymerization, enabling the creation of tailored methacrylic polymers with specific performance characteristics. The compound is typically stabilized to control its tendency to polymerize and requires careful handling to avoid contact with moisture.
It supports the development of advanced materials in coatings, optics, and medical applications where precise control over polymer architecture is essential. Aure Chemical provides material with consistent specifications to meet the demands of industrial polymerization processes. Storage under inert atmosphere or with appropriate stabilizers helps preserve product integrity during transport and use.
