Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (2R,4R)-Pentane-2,4-diylbis(bis(3,5-dimethylphenyl)phosphine) (CAS 217648-63-0), a certified reference material (molecular formula C37H46P2, MW 552.71 g/mol) for analytical method development and quality control.
The molecular framework of (2R,4R)-Pentane-2,4-diylbis(bis(3,5-dimethylphenyl)phosphine) (C37H46P2) is characterized by organophosphorus functionality, 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).
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.
