CATO supplies (11bR)-4-Hydroxy-2,6-bis(2,3,4,5,6-pentafluorophenyl)-4-oxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin (CAS 1284293-45-3), a certified reference material (molecular formula C32H11F10O4P, MW 680.39 g/mol) for analytical method development and quality control.
The molecular framework of (11bR)-4-Hydroxy-2,6-bis(2,3,4,5,6-pentafluorophenyl)-4-oxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin (C32H11F10O4P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), (11bR)-4-Hydroxy-2,6-bis(2,3,4,5,6-pentafluorophenyl)-4-oxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin 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.
