Description
CATO manufactures Gold, (pentachlorophenolato)(triphenylphosphine)- 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.
Gold, (pentachlorophenolato)(triphenylphosphine)- (CAS 118153-91-6) is a high-purity analytical reference standard with the molecular formula C24H15AuCl5OP and a molecular weight of 724.58 g/mol.
Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, Gold, (pentachlorophenolato)(triphenylphosphine)- is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 724.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
