Pyrazines

Pyrazines are organic compounds with a six-membered ring containing two nitrogen atoms in adjacent positions. They contribute to the characteristic aroma and flavor of roasted foods, coffee, and chocolate. In chemistry, pyrazines are important building blocks for various organic compounds. Their distinct odor often resembles roasted nuts or earthy notes.
