2-Chloro-7-methoxyquinazolin-4(3H)-one CAS 20197-98-2

Description

Compared with other compounds in its class, the molecular weight of 210.62 g/mol gives 2-Chloro-7-methoxyquinazolin-4(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Chloro-7-methoxyquinazolin-4(3H)-one (CAS 20197-98-2), a certified reference material (molecular formula C9H7ClN2O2, MW 210.62 g/mol) for analytical method development and quality control.

The molecular framework of 2-Chloro-7-methoxyquinazolin-4(3H)-one (C9H7ClN2O2) 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.

CATO manufactures 2-Chloro-7-methoxyquinazolin-4(3H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
