Chemical Structure
Description
The molecular framework of (1,1,1-Trifluoromethanesulfonato-κO)(triphenylphosphine)gold (C19H15AuF3O3PS) is characterized by a steroid core, a sulfone group, a phosphonate group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
(1,1,1-Trifluoromethanesulfonato-κO)(triphenylphosphine)gold (CAS 156397-47-6), molecular formula C19H15AuF3O3PS and molecular weight 608.32 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.
