7-Chloro-3-methylquinoxalin-2(1H)-one CAS 17796-60-0

Description

The occurrence of 7-Chloro-3-methylquinoxalin-2(1H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 7-Chloro-3-methylquinoxalin-2(1H)-one (CAS 17796-60-0), a certified reference material (molecular formula C9H7ClN2O, MW 194.62 g/mol) for analytical method development and quality control.

7-Chloro-3-methylquinoxalin-2(1H)-one (C9H7ClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 7-Chloro-3-methylquinoxalin-2(1H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
