Chemical Structure

4-chloro-8-methoxy-2-methyl-quinazoline CAS 154288-17-2 chemical structure

Description

4-chloro-8-methoxy-2-methyl-quinazoline (C10H19ClN2O) contains an amide group, a hydroxyl group, an ether linkage, 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.

4-chloro-8-methoxy-2-methyl-quinazoline (CAS 154288-17-2), molecular formula C10H19ClN2O and molecular weight 218.72 g/mol, is a CATO reference standard with documented purity and traceability.

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.
