Chemical Structure
Description
The occurrence of 2-Chloroquinazoline 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.
2-Chloroquinazoline (CAS 6141-13-5) is a high-purity analytical reference standard with the molecular formula C8H5ClN2 and a molecular weight of 164.59 g/mol.
Based on its molecular formula C8H5ClN2, 2-Chloroquinazoline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 164.59 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
