Isoprene, 99%, stab. with ca 0.02% 4-tert-butylcatechol

Description

CAS: 78-79-5 | C5H8 | 68.119 g/mol

Isoprene is used in to prepare synthetic version of natural rubber by polymerization using Ziegler catalysts. It is a basic building block for terpenes especially carotenes, terpenoids, retinol, vitamin-A and tocopherol (Vitamin-E). It finds applications in medical equipments, toys, baby bottle nipples, shoe soles, elastic films and threads for golf balls. Copolymer prepares in association with styrene is used in pressure sensitive adhesives.

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.
