1-(Quinoxalin-5-yl)ethanone CAS 89334-34-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(Quinoxalin-5-yl)ethanone.

1-(Quinoxalin-5-yl)ethanone (CAS 89334-34-9) is a high-purity analytical reference standard with the molecular formula C10H8N2O and a molecular weight of 172.18 g/mol.

1-(Quinoxalin-5-yl)ethanone (C10H8N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 1-(Quinoxalin-5-yl)ethanone 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.
