Methylmagnesium bromide, 3M in ether, packaged under Argon in resealable ChemSeal™ bottles

Description

CAS: 75-16-1 | CH3BrMg | 119.24 g/mol

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.

Applications
Methylmagnesium bromide, 3M in ether has the wide range of applications in organic synthesis. Alkylation of aldehydes and ketones is the most common applications of Grignard reagent. It is a strong nucleophile that can form new carbon-carbon bonds. Also like organolithium compounds, it is useful to form carbon-heteroatom bonds.

Solubility
Soluble in ether, toluene and tetrahydrfuran. Insoluble in hydrocarbons.

Notes
It is highly flammable and reacts with moisture or water to form methane gas, so it should be stored in tightly closed containers.
