Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(SP-4-2)-Trimethyl(methyldiphenylphosphine)gold (CAS 52170-97-5) is a high-purity analytical reference standard with the molecular formula C16H22AuP and a molecular weight of 442.29 g/mol.
(SP-4-2)-Trimethyl(methyldiphenylphosphine)gold (C16H22AuP) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures (SP-4-2)-Trimethyl(methyldiphenylphosphine)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.
