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 (E)-((1,2-Diphenylethene-1,2-diyl)bis(4,1-phenylene))diboronic acid (CAS 1239512-91-4), a certified reference material (molecular formula C26H22B2O4, MW 420.07 g/mol) for analytical method development and quality control.
The molecular framework of (E)-((1,2-Diphenylethene-1,2-diyl)bis(4,1-phenylene))diboronic acid (C26H22B2O4) is characterized by a steroid core, 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).
As a certified reference material (CRM), (E)-((1,2-Diphenylethene-1,2-diyl)bis(4,1-phenylene))diboronic acid 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.
