Chemical Structure

3-(5-Ethoxy-1H-1,2,4-triazol-3-yl)-N-methylbenzenesulfonamide CAS 62036-17-3 chemical structure

Description

The occurrence of 3-(5-Ethoxy-1H-1,2,4-triazol-3-yl)-N-methylbenzenesulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(5-Ethoxy-1H-1,2,4-triazol-3-yl)-N-methylbenzenesulfonamide (CAS 62036-17-3), molecular formula C11H14N4O3S and molecular weight 282.32 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-(5-Ethoxy-1H-1,2,4-triazol-3-yl)-N-methylbenzenesulfonamide (C11H14N4O3S) 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 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 282.32 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
