Chemical Structure
Description
The occurrence of 2-Methyl-5,8-bis(trifluoromethyl)quinoxaline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Methyl-5,8-bis(trifluoromethyl)quinoxaline (CAS 1351516-09-0) is a high-purity analytical reference standard with the molecular formula C11H6F6N2 and a molecular weight of 280.17 g/mol.
The molecular framework of 2-Methyl-5,8-bis(trifluoromethyl)quinoxaline (C11H6F6N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Methyl-5,8-bis(trifluoromethyl)quinoxaline 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.
