Chemical Structure

2-Isopropyl-3-methyl-1,2-dihydroquinoxaline CAS 105340-03-2 chemical structure

Description

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.

2-Isopropyl-3-methyl-1,2-dihydroquinoxaline (CAS 105340-03-2) is a high-purity analytical reference standard with the molecular formula C12H16N2 and a molecular weight of 188.27 g/mol.

The molecular framework of 2-Isopropyl-3-methyl-1,2-dihydroquinoxaline (C12H16N2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 2-Isopropyl-3-methyl-1,2-dihydroquinoxaline 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.
