(2,7-Di-tert-butyl-9,9-dimethyl-5-((R)-methyl(phenyl)phosphaneyl)-9H-xanthen-4-yl)(methyl)(phenyl)phosphane (CAS 201226-88-2), molecular formula C37H44OP2 and molecular weight 566.69 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C37H44OP2, (2,7-Di-tert-butyl-9,9-dimethyl-5-((R)-methyl(phenyl)phosphaneyl)-9H-xanthen-4-yl)(methyl)(phenyl)phosphane contains organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 566.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 (2,7-Di-tert-butyl-9,9-dimethyl-5-((R)-methyl(phenyl)phosphaneyl)-9H-xanthen-4-yl)(methyl)(phenyl)phosphane 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.
