N-(5-Chloro-4-cyclopropoxypyridin-3-yl)methanesulfonamide CAS 1243349-54-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(5-Chloro-4-cyclopropoxypyridin-3-yl)methanesulfonamide.

N-(5-Chloro-4-cyclopropoxypyridin-3-yl)methanesulfonamide (CAS 1243349-54-3) is a high-purity analytical reference standard with the molecular formula C9H11ClN2O3S and a molecular weight of 262.71 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, N-(5-Chloro-4-cyclopropoxypyridin-3-yl)methanesulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), N-(5-Chloro-4-cyclopropoxypyridin-3-yl)methanesulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
