Chemical Structure
Description
CATO supplies (1,2,5-Oxadiazole-3,4-diyl)bis(phenylmethanone) (CAS 10349-12-9), a certified reference material (molecular formula C16H10N2O3, MW 278.26 g/mol) for analytical method development and quality control.
The molecular framework of (1,2,5-Oxadiazole-3,4-diyl)bis(phenylmethanone) (C16H10N2O3) 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 the protonation state of its nitrogen-containing groups, 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).
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), (1,2,5-Oxadiazole-3,4-diyl)bis(phenylmethanone) 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.
