2,4'-Dibromoacetophenone, 98+%

Description

CAS: 99-73-0 | C8H6Br2O | 277.943 g/mol

2,4'-Dibromoacetophenone is used as a reagent for analysis of fatty acids by HPLC as 4-bromophenacyl esters, for use in the protection of phenols and carboxylic acids. It undergoes condensation reactions with aldehydes in the presence of SnCl2 or SmI3 to afford α,β-unsaturated ketones. It is also useful in the esterification of carboxylic acids.

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.
