Description

CAS: 622-97-9 | C9H10 | 118.18 g/mol

4-Methylstyrene is used as a monomer for polyesters and in plastics production. It is also used as an intermediate in paint and coating additives. Further, it is used with other vinyltoluene isomers (3-vinyltoluene) as monomers for the preparation of poly(vinyltoluene). In addition to this, it is employed as a bi- ligand in the preparation of cationic, two-coordinate triphenylphosphine-gold(I)-pi complexes. Further, it is involved in Heck coupling reactions with chlorobenzene.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
