Chemical Structure

methyl 3-chloroquinoxaline-6-carboxylate CAS 948833-63-4 chemical structure

Description

The occurrence of methyl 3-chloroquinoxaline-6-carboxylate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies methyl 3-chloroquinoxaline-6-carboxylate (CAS 948833-63-4), a certified reference material (molecular formula C10H17ClN2O2, MW 232.71 g/mol) for analytical method development and quality control.

The molecular framework of methyl 3-chloroquinoxaline-6-carboxylate (C10H17ClN2O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), methyl 3-chloroquinoxaline-6-carboxylate 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.
