Quinazoline derivatives

Quinazoline derivatives contain quinazoline, an aromatic bicyclic heterocycle formed by a benzene ring fused to a pyrimidine ring. Substitution can occur on either ring. Quinazolinones, reduced analogues and positional isomers are distinct structures; salts are distinct chemical forms.

Defined quinazolines are used as heteroaromatic building blocks and studied in synthetic and medicinal chemistry. The scaffold alone does not establish biological activity or end use. Verify the full name, CAS number, molecular formula, oxidation state, substitution pattern and structure. For an unlisted analogue, provide an exact structure or identifier with your custom-synthesis enquiry.
