N-(2-Chloro-5-cyclopropoxypyridin-4-yl)methanesulfonamide CAS 1243474-27-2

Description

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.

N-(2-Chloro-5-cyclopropoxypyridin-4-yl)methanesulfonamide (CAS 1243474-27-2), molecular formula C9H11ClN2O3S and molecular weight 262.71 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(2-Chloro-5-cyclopropoxypyridin-4-yl)methanesulfonamide (C9H11ClN2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
