Chemical Structure
Description
The occurrence of (2-Methyl-2-propanethiolato)(triphenylphosphine)gold is closely related to sulfur-containing functionality, organophosphorus functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2-Methyl-2-propanethiolato)(triphenylphosphine)gold (CAS 122711-31-3), molecular formula C22H24AuPS and molecular weight 548.43 g/mol, is a CATO reference standard with documented purity and traceability.
(2-Methyl-2-propanethiolato)(triphenylphosphine)gold (C22H24AuPS) contains sulfur-containing functionality, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
