2,4-Dichloro-7,8-dimethoxyquinazoline CAS 61948-62-7

Description

2,4-Dichloro-7,8-dimethoxyquinazoline (C10H8Cl2N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

2,4-Dichloro-7,8-dimethoxyquinazoline (CAS 61948-62-7) is a high-purity analytical reference standard with the molecular formula C10H8Cl2N2O2 and a molecular weight of 259.09 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
