2-Oxo-N-(p-tolyl)oxazolidine-3-sulfonamide CAS 340185-08-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2-Oxo-N-(p-tolyl)oxazolidine-3-sulfonamide (CAS 340185-08-2) is a high-purity analytical reference standard with the molecular formula C10H12N2O4S and a molecular weight of 256.28 g/mol.

2-Oxo-N-(p-tolyl)oxazolidine-3-sulfonamide (C10H12N2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
