Chemical Structure
Description
As a certified reference material (CRM), 2-(3-Oxo-3,4-dihydroquinoxalin-2(1H)-ylidene)-2-phenylacetonitrile 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.
2-(3-Oxo-3,4-dihydroquinoxalin-2(1H)-ylidene)-2-phenylacetonitrile (CAS 68350-66-3) is a high-purity analytical reference standard with the molecular formula C16H11N3O and a molecular weight of 261.28 g/mol.
The molecular framework of 2-(3-Oxo-3,4-dihydroquinoxalin-2(1H)-ylidene)-2-phenylacetonitrile (C16H11N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
