1-Cyclohexyl-2,3-dioxo-1,2,3,4-tetrahydroquinoxaline-6-carboxylic acid CAS 1038385-71-5

Description

CATO supplies 1-Cyclohexyl-2,3-dioxo-1,2,3,4-tetrahydroquinoxaline-6-carboxylic acid (CAS 1038385-71-5), a certified reference material (molecular formula C15H16N2O4, MW 288.30 g/mol) for analytical method development and quality control.

The molecular framework of 1-Cyclohexyl-2,3-dioxo-1,2,3,4-tetrahydroquinoxaline-6-carboxylic acid (C15H16N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 1-Cyclohexyl-2,3-dioxo-1,2,3,4-tetrahydroquinoxaline-6-carboxylic acid 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.
