Beige to brownish crystalline powder

Quinazoline was used to study the electrochemical behaviour of quinazoline using modern polarographic and voltammetric methods. It is the basic structural unit of pharmaceuticals and plays an important role in modern synthesis of antitumor drugs.

ChEBI: A mancude organic heterobicyclic parent that is naphthalene in which the carbon atoms at positions 1 and 3 have been replaced by nitrogen atoms.

Genotoxicity of quinazoline was established by bacterial SOS Chromotest (Escherichia Coli).

Purify quinazoline by passage through an activated alumina column in *C6H6 or pet ether (b 40-60o). Distil it under reduced pressure, sublime it under vacuum and crystallise it from pet ether. The picrate has m 188-189o (from MeOH).
