Aminopyrazine Chemical Properties,Uses,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.
