Description

R-(+)-1,2-Bis(diphenylphosphino)propane 67884-32-6 (R)-(+)-BIS-(1,2-DIPHENYLPHOSPHINO)PROPANE;(R)-(+)-PROPHOS;(R)-(+)-PROPYLENEBIS(1,2-DIPHENYLPHOSPHINE);(R)-PROPHOS;R-(+)-1,2-BIS(DIPHENYLPHOSPHINO)PROPANE SC11384 (CAS 67884-32-6) is a high-purity analytical reference standard with the molecular formula C27H50P2 and a molecular weight of 436.63 g/mol.

Based on its molecular formula C27H50P2, R-(+)-1,2-Bis(diphenylphosphino)propane 67884-32-6 (R)-(+)-BIS-(1,2-DIPHENYLPHOSPHINO)PROPANE;(R)-(+)-PROPHOS;(R)-(+)-PROPYLENEBIS(1,2-DIPHENYLPHOSPHINE);(R)-PROPHOS;R-(+)-1,2-BIS(DIPHENYLPHOSPHINO)PROPANE SC11384 contains organophosphorus functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 436.63 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
