What is 2,4'-Dibromoacetophenone?
Chemical properties
2,4'-Dibromoacetophenone is off-white crystals or powder
The Uses of 2,4'-Dibromoacetophenone
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.

What are the applications of Application
GSK-3β Inhibitor VII is a cell-permeable, and non-ATP competitive inhibitor of GSK-3β
General Description
A phenyl α-bromomethyl ketone compound that acts as a cell-permeable, and non-ATP competitive inhibitor of GSK-3β (IC50 = 0.5 μM). This reactive alkylating agent is selective towards GSK-3β and does not affect PKA activity even at concentrations as high as 100 μM.
Biochem/physiol Actions
Cell permeable: yes
Purification Methods
Crystallise the bromide from EtOH (ca 8mL/g). [Beilstein 7 IV 652.]
