2-Amino-3,5-Dibromopyrazine (CAS: 24241-18-7) is mainly used as a pharmaceutical intermediate. 2-Amino-3,5-Dibromopyrazine is used in the preparation of conjugated polymers for neurotoxin detection. 2-Amino-3,5-Dibromopyrazine is an intermediate in the preparation of rho kinase (ROCK) inhibitors. Uses: 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. 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.
