Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1,2-Bis(4-fluorobenzyl)diselane (CAS 57239-58-4), a certified reference material (molecular formula C14H12F2Se2, MW 376.16 g/mol) for analytical method development and quality control.
The molecular framework of 1,2-Bis(4-fluorobenzyl)diselane (C14H12F2Se2) is characterized by fluorine substitution, a polycyclic aromatic system. 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).
As a certified reference material (CRM), 1,2-Bis(4-fluorobenzyl)diselane 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.
