Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(R)-N-((R)-1-(3',5'-Di-tert-butyl-4'-methoxy-[1,1'-biphenyl]-2-yl)-2-(diphenylphosphanyl)ethyl)-2-methylpropane-2-sulfinamide (CAS 1936438-27-5) is a high-purity analytical reference standard with the molecular formula C39H50NO2PS and a molecular weight of 627.86 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, organophosphorus functionality, a hydroxyl group, an ether linkage, (R)-N-((R)-1-(3',5'-Di-tert-butyl-4'-methoxy-[1,1'-biphenyl]-2-yl)-2-(diphenylphosphanyl)ethyl)-2-methylpropane-2-sulfinamide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 627.86 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.
CATO manufactures (R)-N-((R)-1-(3',5'-Di-tert-butyl-4'-methoxy-[1,1'-biphenyl]-2-yl)-2-(diphenylphosphanyl)ethyl)-2-methylpropane-2-sulfinamide 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.
