Chemical Structure

S-benzylcysteine benzyl ester p-toluenesulfonate CAS 73995-16-1 chemical structure

Description

The occurrence of S-benzylcysteine benzyl ester p-toluenesulfonate is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

S-benzylcysteine benzyl ester p-toluenesulfonate (CAS 73995-16-1) is a high-purity analytical reference standard with the molecular formula C17H19NO2SC7H8O3S and a molecular weight of 473.60 g/mol.

The molecular framework of S-benzylcysteine benzyl ester p-toluenesulfonate (C17H19NO2SC7H8O3S) is characterized by a flavonoid core, an amide group, a sulfone group, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures S-benzylcysteine benzyl ester p-toluenesulfonate 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.
