Chemical Structure

(R)-(-)-4,12-Bis(di(3,5-xylyl)phosphino)-[2.2]-paracyclophane CAS 325168-89-6 chemical structure

Description

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.

CATO supplies (R)-(-)-4,12-Bis(di(3,5-xylyl)phosphino)-[2.2]-paracyclophane (CAS 325168-89-6), a certified reference material (molecular formula C48H50P2, MW 688.86 g/mol) for analytical method development and quality control.

Structurally, (R)-(-)-4,12-Bis(di(3,5-xylyl)phosphino)-[2.2]-paracyclophane (C48H50P2) contains organophosphorus functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 24.0, corresponding to approximately 24 ring(s) or double-bond equivalent(s). With a molecular weight of 688.86 g/mol, it falls into the high-molecular-weight range. 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.
