(1R,2S)-2-(3-(3,5-Bis(trifluoromethyl)phenyl)ureido)-1,2-diphenylethyl 2-(diphenylphosphino)benzoate CAS 2767521-32-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1R,2S)-2-(3-(3,5-Bis(trifluoromethyl)phenyl)ureido)-1,2-diphenylethyl 2-(diphenylphosphino)benzoate.

(1R,2S)-2-(3-(3,5-Bis(trifluoromethyl)phenyl)ureido)-1,2-diphenylethyl 2-(diphenylphosphino)benzoate (CAS 2767521-32-2) is a high-purity analytical reference standard with the molecular formula C42H31F6N2O3P and a molecular weight of 756.67 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphonate group, a hydroxyl group, an ether linkage, fluorine substitution, (1R,2S)-2-(3-(3,5-Bis(trifluoromethyl)phenyl)ureido)-1,2-diphenylethyl 2-(diphenylphosphino)benzoate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 756.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
