Propargyl bromide, 97%, 80% w/w in toluene, stab. with magnesium oxide, Thermo Scientific Chemicals

Description

Propargyl bromide is used as an alkylating agent as well as an intermediate for the synthesis of organic compounds, agrochemicals and pharmaceuticals. It reacts with magnesium in presence of ether to get a Grignard reagent namely allenylmagnesium bromide, which on further reaction with propargyl bromide prepares bis-allene 1,2,4,5-hexatetraene. Also, used as metal brightening agents, corrosion inhibitor and soil fumigant.

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.
