The Uses of 2,4-Dibromophenol
2,4-Dibromophenol-13C6 is the labelled version of 2,4-Dibromophenol (D425745), a fundamental starting material for organic synthesis.
Definition
ChEBI: 2,4-dibromophenol is a bromophenol that is phenol in which the hydrogens at positions 2 and 4 have been replaced by bromines. It has a role as a marine metabolite. It is a bromophenol, a dibromobenzene and a brominated flame retardant.

General Description
The electrochemical hydrodehalogenation of 2,4-dibromophenol has been studied by electrochemical reduction in H-cells and solid polymer electrolyte cells using catalyzed cathodes. 2,4-Dibromophenol inhibits the microbial activity in marine sediments.
Purification Methods
Crystallise the phenol from CHCl3 at -40o, or distil it in a vacuum. [Beilstein 6 H 202, 6 I 106, 6 II 188, 6 III 753, 6 IV 1061.]
