Chemical Structure

Ethyl (1R,2S)-1-amino-2-vinylcyclopropane-1-carboxylate 4-methylbenzenesulfonate CAS 1159609-95-6 chemical structure

Description

The molecular framework of Ethyl (1R,2S)-1-amino-2-vinylcyclopropane-1-carboxylate 4-methylbenzenesulfonate (C7H8O3SC8H13NO2) is characterized by a nitrogen-containing heterocyclic scaffold, 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).

Ethyl (1R,2S)-1-amino-2-vinylcyclopropane-1-carboxylate 4-methylbenzenesulfonate (CAS 1159609-95-6) is a high-purity analytical reference standard with the molecular formula C7H8O3SC8H13NO2 and a molecular weight of 327.39 g/mol.
