white to light yellow crystal powde

Uses

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) inhibitor s.

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

General Description

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.
