rel-(S)-N-((R)-(3,5-Di-tert-butyl-4-methoxyphenyl)(5-(diphenylphosphino)-9,9-dimethyl-9H-xanthen-4-yl)methyl)-2-methylpropane-2-sulfinamide CAS 2828070-48-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including rel-(S)-N-((R)-(3,5-Di-tert-butyl-4-methoxyphenyl)(5-(diphenylphosphino)-9,9-dimethyl-9H-xanthen-4-yl)methyl)-2-methylpropane-2-sulfinamide.

rel-(S)-N-((R)-(3,5-Di-tert-butyl-4-methoxyphenyl)(5-(diphenylphosphino)-9,9-dimethyl-9H-xanthen-4-yl)methyl)-2-methylpropane-2-sulfinamide (CAS 2828070-48-8) is a high-purity analytical reference standard with the molecular formula C46H54NO3PS and a molecular weight of 731.96 g/mol.

The molecular framework of rel-(S)-N-((R)-(3,5-Di-tert-butyl-4-methoxyphenyl)(5-(diphenylphosphino)-9,9-dimethyl-9H-xanthen-4-yl)methyl)-2-methylpropane-2-sulfinamide (C46H54NO3PS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphonate group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
