Phosphine, 1,1′-[(1R)-2,2′,3,3′-tetrahydro-3,3,3′,3′,5,5′-hexamethyl-1,1′-spirobi[1H-indene]-7,7′-diyl]bis[1,1-diphenyl- CAS 2213471-14-6

Description

Phosphine, 1,1′-[(1R)-2,2′,3,3′-tetrahydro-3,3,3′,3′,5,5′-hexamethyl-1,1′-spirobi[1H-indene]-7,7′-diyl]bis[1,1-diphenyl- (CAS 2213471-14-6) is a high-purity analytical reference standard with the molecular formula C47H46P2 and a molecular weight of 672.82 g/mol.

Phosphine, 1,1′-[(1R)-2,2′,3,3′-tetrahydro-3,3,3′,3′,5,5′-hexamethyl-1,1′-spirobi[1H-indene]-7,7′-diyl]bis[1,1-diphenyl- (C47H46P2) 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.

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.
