Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 272.75 g/mol gives 2-[(2-Chlorophenyl)sulfanyl]quinoxaline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-[(2-Chlorophenyl)sulfanyl]quinoxaline (CAS 338394-57-3) is a high-purity analytical reference standard with the molecular formula C14H9ClN2S and a molecular weight of 272.75 g/mol.
The molecular framework of 2-[(2-Chlorophenyl)sulfanyl]quinoxaline (C14H9ClN2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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.
As a certified reference material (CRM), 2-[(2-Chlorophenyl)sulfanyl]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.
