Chemical Structure
Description
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.
N-(2,3-dichlorophenyl)-N-(methylsulfonyl)glycine (CAS 432003-31-1), molecular formula C9H9Cl2NO4S and molecular weight 298.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, N-(2,3-dichlorophenyl)-N-(methylsulfonyl)glycine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
