4-Methylstyrene(CAS NO:622-97-9)

Properties: An organic compound existing as a colorless liquid. Melting point: -34.2°C; flash point: 60°C; initial boiling point: 172.8°C. The unstabilized form of 4-methylstyrene is flammable and prone to polymerization, requiring stabilization before storage and transportation. Its vapor can form an explosive mixture with air; contact with an open flame or high heat can trigger combustion and explosion. The autoignition temperature is 575°C.

Uses: Primarily used in industrial and scientific research fields, where strict control of its stabilization state is essential. As a monomer, it is used in the production of p-methylstyrene resins and can replace styrene in the synthesis of poly(p-methylstyrene)-poly(p-methylstyrene) triblock copolymers. It serves as one of the monomers in coating manufacturing and synthetic rubber production. It can also be used as an analytical reagent or chemical intermediate.
