Chemical Structure
Description
The occurrence of 2-Chloro-6,7-dimethoxy-1,4-dihydroquinazoline is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Chloro-6,7-dimethoxy-1,4-dihydroquinazoline (CAS 80591-17-9) is a high-purity analytical reference standard with the molecular formula C10H11ClN2O2 and a molecular weight of 226.66 g/mol.
The molecular framework of 2-Chloro-6,7-dimethoxy-1,4-dihydroquinazoline (C10H11ClN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
