Chemical Structure
Description
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.
(2-Methylphenyl)(triphenylphosphine)gold (CAS 925253-65-2), molecular formula C25H22AuP and molecular weight 550.38 g/mol, is a CATO reference standard with documented purity and traceability.
(2-Methylphenyl)(triphenylphosphine)gold (C25H22AuP) contains 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
