Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 459.34 g/mol gives (Phenylethynyl)(triisopropylphosphoranyl)gold distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (Phenylethynyl)(triisopropylphosphoranyl)gold (CAS 89989-63-9), a certified reference material (molecular formula C17H27AuP, MW 459.34 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, an aromatic ring system, (Phenylethynyl)(triisopropylphosphoranyl)gold is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 459.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures (Phenylethynyl)(triisopropylphosphoranyl)gold under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
