Chemical Structure
Description
Methyl N-(methylsulfonyl)-N-(o-tolyl)glycinate (CAS 333321-46-3) is a high-purity analytical reference standard with the molecular formula C11H15NO4S and a molecular weight of 257.31 g/mol.
The molecular framework of Methyl N-(methylsulfonyl)-N-(o-tolyl)glycinate (C11H15NO4S) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
