N-((3-methyl-1,2,4-oxadiazol-5-yl)methyl)benzenesulfonamide CAS 1219904-23-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-((3-methyl-1,2,4-oxadiazol-5-yl)methyl)benzenesulfonamide.

N-((3-methyl-1,2,4-oxadiazol-5-yl)methyl)benzenesulfonamide (CAS 1219904-23-0) is a high-purity analytical reference standard with the molecular formula C10H11N3O3S and a molecular weight of 253.28 g/mol.

The molecular framework of N-((3-methyl-1,2,4-oxadiazol-5-yl)methyl)benzenesulfonamide (C10H11N3O3S) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
