Quinoxaline derivatives

Quinoxaline derivatives contain quinoxaline, an aromatic bicyclic heterocycle formed by a benzene ring fused to a pyrazine ring. This 1,4-benzodiazine is a positional isomer of quinazoline. Quinoxalinones, reduced analogues and substituted quinoxalines are related but chemically distinct.

Quinoxaline scaffolds are used as heteroaromatic building blocks and studied in synthetic, medicinal and materials chemistry. These are compound-specific contexts, not proof of a shared activity or benefit. Verify the full name, CAS number, molecular formula, substitution positions and structure. For an unlisted target, provide an exact structure or identifier with your custom-synthesis enquiry.
