Chemical Structure

(S)-(+)-S-Methyl -S-phenylsulfoximine (S)-S-methylsulfonimidoylbenzene 33903-50-3 CAS 33903-50-3 chemical structure

Description

The molecular framework of (S)-(+)-S-Methyl -S-phenylsulfoximine (S)-S-methylsulfonimidoylbenzene 33903-50-3 (C7H15NOS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.

(S)-(+)-S-Methyl -S-phenylsulfoximine (S)-S-methylsulfonimidoylbenzene 33903-50-3 (CAS 33903-50-3) is a high-purity analytical reference standard with the molecular formula C7H15NOS and a molecular weight of 161.27 g/mol.

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.
