Chemical Structure

N-Acetyl-S-(2-ethoxycarbonylethyl-1-methyl)-L-cysteine, Dicyclohexylammonium Salt CAS 33297-48-2 chemical structure

Description

The occurrence of N-Acetyl-S-(2-ethoxycarbonylethyl-1-methyl)-L-cysteine, Dicyclohexylammonium Salt is closely related to a steroid 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.

N-Acetyl-S-(2-ethoxycarbonylethyl-1-methyl)-L-cysteine, Dicyclohexylammonium Salt (CAS 33297-48-2) is a high-purity analytical reference standard with the molecular formula C11H19NO5SC12H23N and a molecular weight of 458.66 g/mol.

The molecular framework of N-Acetyl-S-(2-ethoxycarbonylethyl-1-methyl)-L-cysteine, Dicyclohexylammonium Salt (C11H19NO5SC12H23N) is characterized by a steroid 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.
