Chemical Structure
Description
As a certified reference material (CRM), 2-Phenylbenzo[d][1,2]selenazol-3(2H)-one 1-oxide 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.
CATO supplies 2-Phenylbenzo[d][1,2]selenazol-3(2H)-one 1-oxide (CAS 104473-83-8), a certified reference material (molecular formula C13H9NO2Se, MW 290.18 g/mol) for analytical method development and quality control.
The molecular framework of 2-Phenylbenzo[d][1,2]selenazol-3(2H)-one 1-oxide (C13H9NO2Se) 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.
