Owing to organophosphorus functionality, an aromatic ring system, 1,1,1-Tris(diphenylphosphinomethyl)ethane 22031-12-5 1,1,1-TRIS(DIPHENYLPHOSPHINOMETHYL)ETHANE;1,3-BIS(DIPHENYLPHOSPHINO)-2-(DIPHENYLPHOSPHINO)METHYL-2-METHYLPROPANE;PHENYL TRIPHOS;TRIPHOS SC11533 is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 660.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
1,1,1-Tris(diphenylphosphinomethyl)ethane 22031-12-5 1,1,1-TRIS(DIPHENYLPHOSPHINOMETHYL)ETHANE;1,3-BIS(DIPHENYLPHOSPHINO)-2-(DIPHENYLPHOSPHINO)METHYL-2-METHYLPROPANE;PHENYL TRIPHOS;TRIPHOS SC11533 (CAS 22031-12-5), molecular formula C41H75P3 and molecular weight 660.96 g/mol, is a CATO reference standard with documented purity and traceability.
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.
