Description
As a certified reference material (CRM), 1314446-39-3 2-(5-Chloro-1H-indol-3-yl)-6,7-dimethyl-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.
1314446-39-3 2-(5-Chloro-1H-indol-3-yl)-6,7-dimethyl-quinoxaline (CAS 1314446-39-3) is a high-purity analytical reference standard with the molecular formula C18H14ClN3 and a molecular weight of 307.78 g/mol.
The molecular framework of 1314446-39-3 2-(5-Chloro-1H-indol-3-yl)-6,7-dimethyl-quinoxaline (C18H14ClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
