N-Methylmaleimide(CAS: 930-88-1)

N-Methylmaleimide (CAS: 930-88-1) is a colorless to light yellow liquid with a strong, pungent odor. It has a molecular weight of 140.12 g/mol and a melting point of -73°C. It is highly soluble in water and organic solvents. Chemically, it is reactive, particularly towards nucleophiles, and is often used in polymerization and as a crosslinking agent.

N-Methylmaleimide is typically synthesized by the reaction of maleic anhydride with methylamine. This process involves heating maleic anhydride with methylamine in the presence of a Lewis acid catalyst such as aluminum chloride to promote the reaction. The yield and selectivity are good, with a high purity product obtained.

N-Methylmaleimide (CAS: 930-88-1) is widely used in the pharmaceutical industry for drug synthesis, in polymer chemistry for producing copolymers, in the sensor industry for gas detection, and in the semiconductor industry for photolithography. Its reactivity makes it valuable in these applications.

When handling N-Methylmaleimide (CAS: 930-88-1), use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work in a well-ventilated area or fume hood. Store in a cool, dry place away from heat sources and incompatible materials. Follow standard waste disposal procedures and consult the Safety Data Sheet (SDS) for specific guidelines.
