3-Cyclopropoxy-5-(methylsulfonamido)pyridine-2-sulfonamide CAS 1243408-31-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Cyclopropoxy-5-(methylsulfonamido)pyridine-2-sulfonamide.

CATO supplies 3-Cyclopropoxy-5-(methylsulfonamido)pyridine-2-sulfonamide (CAS 1243408-31-2), a certified reference material (molecular formula C9H13N3O5S2, MW 307.35 g/mol) for analytical method development and quality control.

Structurally, 3-Cyclopropoxy-5-(methylsulfonamido)pyridine-2-sulfonamide (C9H13N3O5S2) 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 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 307.35 g/mol, it falls into the moderately-high-molecular-weight range. 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.
