Description
CATO supplies Chloro[2-(dicyclohexylphosphino)-3,6-dimethoxy-2′,4′,6′-triisopropyl-1,1′-biphenyl]gold(I) (CAS 1334547-75-9), a certified reference material (molecular formula C35H65O2PAuCl, MW 781.30 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Chloro[2-(dicyclohexylphosphino)-3,6-dimethoxy-2′,4′,6′-triisopropyl-1,1′-biphenyl]gold(I) is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 781.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Chloro[2-(dicyclohexylphosphino)-3,6-dimethoxy-2′,4′,6′-triisopropyl-1,1′-biphenyl]gold(I) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
