Chemical Structure
Description
The molecular framework of 2,3-Dimethyl-1,2,3,4-tetrahydroquinoxaline (C10H14N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 2,3-Dimethyl-1,2,3,4-tetrahydroquinoxaline (CAS 13311-77-8), a certified reference material (molecular formula C10H14N2, MW 162.23 g/mol) for analytical method development and quality control.
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), 2,3-Dimethyl-1,2,3,4-tetrahydroquinoxaline 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.
