Description

Compared with other compounds in its class, the molecular weight of 698.77 g/mol gives (11bR,11′bR)-4,4′-(1,2-Phenylene)bis[4,5-dihydro-3H-dinaphtho[2,1-c:1′,2′-e]phosphepin] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (11bR,11′bR)-4,4′-(1,2-Phenylene)bis[4,5-dihydro-3H-dinaphtho[2,1-c:1′,2′-e]phosphepin] (CAS 253311-88-5), a certified reference material (molecular formula C50H36P2, MW 698.77 g/mol) for analytical method development and quality control.

(11bR,11′bR)-4,4′-(1,2-Phenylene)bis[4,5-dihydro-3H-dinaphtho[2,1-c:1′,2′-e]phosphepin] (C50H36P2) contains organophosphorus functionality, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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,11′bR)-4,4′-(1,2-Phenylene)bis[4,5-dihydro-3H-dinaphtho[2,1-c:1′,2′-e]phosphepin] 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.
