Chemical Structure
Description
The occurrence of 2-Chloro-4-(4-chloro-1h-pyrazol-1-yl)quinazoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Chloro-4-(4-chloro-1h-pyrazol-1-yl)quinazoline (CAS 1496101-43-9), a certified reference material (molecular formula C11H6Cl2N4, MW 265.10 g/mol) for analytical method development and quality control.
2-Chloro-4-(4-chloro-1h-pyrazol-1-yl)quinazoline (C11H6Cl2N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
