Description

CAS: 536-74-3 | C8H6 | 102.136 g/mol

Phenylacetylene is involved in the preparation of styrene by reduction using Lindlar catalyst. It is used to study the mechanism of the palladium-catalyzed phenyl acetylene oxidative carbonylation reaction. It is also used in the polymerization process to prepare polyphenylacetylene namely 1,2,4-triphenylbenzene and 1,3,5-triphenylbenzene.

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.
