4-chloro-8-methoxyquinazolin-2-amine CAS 124309-87-1

Description

The occurrence of 4-chloro-8-methoxyquinazolin-2-amine is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-chloro-8-methoxyquinazolin-2-amine (CAS 124309-87-1) is a high-purity analytical reference standard with the molecular formula C9H18ClN3O and a molecular weight of 219.71 g/mol.

Based on its molecular formula C9H18ClN3O, 4-chloro-8-methoxyquinazolin-2-amine contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 219.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
