Chemical Structure
Description
(2-Phenylethynyl)(trimethylphosphine)gold (C11H14AuP) contains organophosphorus functionality, an aromatic ring 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).
(2-Phenylethynyl)(trimethylphosphine)gold (CAS 89989-62-8) is a high-purity analytical reference standard with the molecular formula C11H14AuP and a molecular weight of 374.17 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
