Quinazoline Chemical Properties,Usage,Production

Chemical Properties

Beige to brownish crystalline powder

Uses

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.

Definition

ChEBI: A mancude organic heterobicyclic parent that is naphthalene in which the carbon atoms at positions 1 and 3 have been replaced by nitrogen atoms.

General Description

Quinazolines has applications in medicinal chemistry due to their antibacterial, antifungal, anticonvulsant, anti-inflammatory and antitumor activities. It is the basic structural unit of pharmaceuticals and plays an important role in modern synthesis of antitumor drugs.

Biochem/physiol Actions

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

Purification Methods

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).
