Aminopyrazine Chemical Properties,Usage,Production

Chemical Properties

SLIGHTLY YELLOW TO BEIGE CRYSTALLINE POWDER

Uses

2-Aminopyrazine acts as a raw material in a four-component synthesis of imidazolidines. It is also used as an intermediate in synthetic chemistry. In addition, 2-aminopyrazine can be reacted with α-ketohydroximoyl chlorides to form 3-nitrosoimidazo[1,2-a]pyrazines.

Application

2-Aminopyrazine is a synthetic intermediate useful for pharmaceutical synthesis. It is used to synthesize favipiravir and substrate in a four-component synthesis of imidazolidines.

Definition

ChEBI: Aminopyrazine is a member of pyrazines.
