Chemical Structure
Description
The occurrence of (E)-2-chloro-4-(2-(2-fluorobenzylidene)hydrazinyl)quinazoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (E)-2-chloro-4-(2-(2-fluorobenzylidene)hydrazinyl)quinazoline (CAS 339025-94-4), a certified reference material (molecular formula C15H10ClFN4, MW 300.72 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, (E)-2-chloro-4-(2-(2-fluorobenzylidene)hydrazinyl)quinazoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
