Description

Isobutenylbenzene (CAS 768-49-0) is a high-purity organic compound with the molecular formula C₁₀H₁₂ and IUPAC name 2-methylprop-1-enylbenzene. This colorless to pale yellow liquid is a versatile building block in organic synthesis, particularly in the production of polymers, resins, and specialty chemicals. With a molecular weight of 132.20 g/mol and a boiling point of approximately 170-172°C, it is characterized by its reactive isobutenyl group attached to a benzene ring, making it valuable for electrophilic addition and polymerization reactions. Our Isobutenylbenzene is rigorously tested for purity (typically ≥98% by GC) and is supplied in tightly sealed containers to ensure stability and prevent degradation. Suitable for research and industrial applications, it is an essential reagent for chemists working in material science, pharmaceuticals, and fine chemical synthesis.
