1-Bromobutane, 98+%

Description

CAS: 109-65-9 | C4H9Br | 137.02 g/mol

1-Bromobutane is used as an intermediate in organic synthesis and as a solvent for cleaning and degreasing. It acts as an alkylating agent as well as to prepare organometallic compounds such as n-butyllithium. It is also involved in the synthesis of procaine and tetracaine. It reacts with magnesium metal to prepare the Grignard reagent, which is used to form carbon-carbon bonds.

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.
