(11bR)-4-Hydroxy-2,6-bis(4-methoxyphenyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-oxide CAS 695162-88-0 chemical structure

Description

CATO supplies (11bR)-4-Hydroxy-2,6-bis(4-methoxyphenyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-oxide (CAS 695162-88-0), a certified reference material (molecular formula C34H25O6P, MW 560.53 g/mol) for analytical method development and quality control.

The molecular framework of (11bR)-4-Hydroxy-2,6-bis(4-methoxyphenyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-oxide (C34H25O6P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), (11bR)-4-Hydroxy-2,6-bis(4-methoxyphenyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-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.
