Product Describtion: 2-Amino-3,5-dibromopyrazine can be synthesized from 2-aminopyrazine via bromination using N-bromosuccinimide (NBS). It reacts with sodium dicyanocuprate to form a mixture of mono and dicyanation products. The formation of 2-aminothiazolopyrazines by reacting 2-amino-3,5-dibromopyrazine with isothiocyanates has been reported. Product Application： 2-Amino-3,5-dibromopyrazine may be used in the synthesis of: 2-amino-5-bromopyrazin-3-thiol 2-amino-3,5-bis(p-methoxyphenyl)-1,4-pyrazine 3,7-dihydroimidazo[1,2a]pyrazine-3-ones
