Description

Compared with other compounds in its class, the molecular weight of 244.08 g/mol gives 2,6-Dichloro-7-methoxyquinazolin-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,6-Dichloro-7-methoxyquinazolin-4-amine (CAS 79025-77-7), molecular formula C9H7Cl2N3O and molecular weight 244.08 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,6-Dichloro-7-methoxyquinazolin-4-amine (C9H7Cl2N3O) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
