Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 201.24 g/mol gives 2-Ethoxybenzene-1-sulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Ethoxybenzene-1-sulfonamide (CAS 58734-61-5), molecular formula C8H11NO3S and molecular weight 201.24 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Ethoxybenzene-1-sulfonamide (C8H11NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 201.24 g/mol, it falls into the medium-molecular-weight range. 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.
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.
