Chemical Structure
Description
The molecular framework of ((1R,2R,3R,4S)-Bicyclo[2.2.1]hept-5-ene-2,3-diyl)bis(diphenylphosphine oxide) (C31H28O2P2) is characterized by organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, 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).
((1R,2R,3R,4S)-Bicyclo[2.2.1]hept-5-ene-2,3-diyl)bis(diphenylphosphine oxide) (CAS 71075-24-6), molecular formula C31H28O2P2 and molecular weight 494.50 g/mol, is a CATO reference standard with documented purity and traceability.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
