3-Amino-6-bromopyrazin-2(1H)-one features a brominated pyrazinone core with a strategically positioned amino group, enabling direct functionalization in heterocyclic synthesis. This bench-stable scaffold integrates readily into pharmaceutical intermediates and advanced materials, offering high reactivity under standard coupling conditions without requiring protective groups.
3-Amino-6-bromopyrazin-2(1H)-one serves as a versatile building block for heterocyclic synthesis, enabling efficient access to pyrazine-based scaffolds through palladium-catalyzed cross-coupling and nucleophilic substitution reactions. The bromo group facilitates C–C bond formation under standard Suzuki-Miyaura conditions, while the amino functionality offers direct derivatization potential. Its bench-stable crystalline form and compatibility with diverse functional groups make it ideal for medicinal chemistry campaigns and API intermediate development.
