Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 392.66 g/mol gives Chloro(triisopropylphosphine)gold distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Chloro(triisopropylphosphine)gold (CAS 33659-45-9), a certified reference material (molecular formula C9H21AuClP, MW 392.66 g/mol) for analytical method development and quality control.
Chloro(triisopropylphosphine)gold (C9H21AuClP) contains organophosphorus functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
