The molecular framework of 2-Di-t-butylphosphino-3,4,5,6-tetramethyl-2',4',6'-tri-i-propylbiphenyl 857356-94-6 2-DI-T-BUTYLPHOSPHINO-3,4,5,6-TETRAMETHYL-2',4',6'-TRI-I-PROPYLBIPHENYL;2-DI-TERT-BUTYLPHOSPHINO-3,4,5,6-TETRAMETHYL-2',4',6'-TRIISOPROPYL-1,1'-BIPHENYL;2-DI-TERT-BUTYLPHOSPHINO-3,4,5,6-TETRAMETHYL-2',4',6'-TRIISOPROPYLBIPHENYL;DI-TERT-BUTYL(2',4',6'-TRIISOPROPYL-3,4,5,6-TETRAMETHYL-[1,1'-BIPHENYL]-2-YL)PHOSPHINE;ME4 T-BUTYLXPHOS;TETRAMETHYL DI-TBUXPHOS SC11287 (C33H65P) is characterized by organophosphorus functionality. 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 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.
