white to light yellow crystal powde
Uses
4-Nitrobenzyl bromide is used in the synthesis of di and tri-substituted azoles. It is also used in the preparation of N6-Benzyladenosine-5?-uronamides as selective A3 adenosine agonists.
Definition
ChEBI: A C-nitro compound that consists of nitrobenzene bearing a bromomethyl substituent at the para-position.
Purification Methods
Recrystallise the bromide four times from absolute EtOH, then twice from cyclohexane/hexane/*benzene (1:1:1), followed by sublimation at 0.1mm and final recrystallisation from the same solvent mixture. [Lichtin & Rao J Am Chem Soc 83 2417 1961.] It has also been crystallised from pet ether (b 80-100o, 10mL/g, charcoal). It slowly decomposes even when stored in a desiccator in the dark. IRRITANT.
