N-(3-Cyclopropoxy-5-iodopyridin-2-yl)methanesulfonamide CAS 1243446-33-4

Description

Structurally, N-(3-Cyclopropoxy-5-iodopyridin-2-yl)methanesulfonamide (C9H11IN2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution. 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 354.16 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies N-(3-Cyclopropoxy-5-iodopyridin-2-yl)methanesulfonamide (CAS 1243446-33-4), a certified reference material (molecular formula C9H11IN2O3S, MW 354.16 g/mol) for analytical method development and quality control.

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.
