Chemical Structure

(2S,4E,6S)-2,4,6-Trimethyl-7-oxo-7-[(4S)-2-oxo-4-(phenylmethyl)-3-oxazolidinyl]-4-heptenoic Acid Ethyl Ester CAS 943858-30-8 chemical structure

Description

The occurrence of (2S,4E,6S)-2,4,6-Trimethyl-7-oxo-7-[(4S)-2-oxo-4-(phenylmethyl)-3-oxazolidinyl]-4-heptenoic Acid Ethyl Ester is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2S,4E,6S)-2,4,6-Trimethyl-7-oxo-7-[(4S)-2-oxo-4-(phenylmethyl)-3-oxazolidinyl]-4-heptenoic Acid Ethyl Ester (CAS 943858-30-8) is a high-purity analytical reference standard with the molecular formula C22H29NO5 and a molecular weight of 387.47 g/mol.

The molecular framework of (2S,4E,6S)-2,4,6-Trimethyl-7-oxo-7-[(4S)-2-oxo-4-(phenylmethyl)-3-oxazolidinyl]-4-heptenoic Acid Ethyl Ester (C22H29NO5) is characterized by a flavonoid core, an amide 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).
