6-Methylquinoxaline CAS 6344-72-5 chemical structure

Description

As a certified reference material (CRM), 6-Methylquinoxaline 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.

6-Methylquinoxaline (CAS 6344-72-5) is a high-purity analytical reference standard with the molecular formula C9H8N2 and a molecular weight of 144.17 g/mol.

6-Methylquinoxaline (C9H8N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
