Chemical Structure

Diphenyl benzyl((1S,2R)-2-((4-chlorophenyl)thio)-1,2-diphenylethyl)phosphoramidite CAS 2137862-61-2 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 Diphenyl benzyl((1S,2R)-2-((4-chlorophenyl)thio)-1,2-diphenylethyl)phosphoramidite.

Diphenyl benzyl((1S,2R)-2-((4-chlorophenyl)thio)-1,2-diphenylethyl)phosphoramidite (CAS 2137862-61-2) is a high-purity analytical reference standard with the molecular formula C39H33ClNO2PS and a molecular weight of 646.18 g/mol.

The molecular framework of Diphenyl benzyl((1S,2R)-2-((4-chlorophenyl)thio)-1,2-diphenylethyl)phosphoramidite (C39H33ClNO2PS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
