Chemical Structure
Description
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.
Gold(1+), (acetonitrile)[dicyclohexyl(2′,6′-dimethoxy[1,1′-biphenyl]-2-yl)phosphine-κP]-, (OC-6-11)-hexafluoroantimonate(1-) (1:1) (CAS 1236160-37-4), molecular formula C28H38AuNO2PF6Sb and molecular weight 884.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Gold(1+), (acetonitrile)[dicyclohexyl(2′,6′-dimethoxy[1,1′-biphenyl]-2-yl)phosphine-κP]-, (OC-6-11)-hexafluoroantimonate(1-) (1:1) (C28H38AuNO2PF6Sb) is characterized by a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution. 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 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).
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.
