5-(propan-2-yloxy)pyridine-3-sulfonamide CAS 1547691-59-7

Description

Compared with other compounds in its class, the molecular weight of 216.26 g/mol gives 5-(propan-2-yloxy)pyridine-3-sulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(propan-2-yloxy)pyridine-3-sulfonamide (CAS 1547691-59-7) is a high-purity analytical reference standard with the molecular formula C8H12N2O3S and a molecular weight of 216.26 g/mol.

5-(propan-2-yloxy)pyridine-3-sulfonamide (C8H12N2O3S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
