Chemical Structure
Description
The occurrence of N-(3-chlorophenyl)-2-(2-oxo-5-(piperidin-1-ylsulfonyl)pyridin-1(2H)-yl)acetamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N-(3-chlorophenyl)-2-(2-oxo-5-(piperidin-1-ylsulfonyl)pyridin-1(2H)-yl)acetamide (CAS 1251593-55-1), a certified reference material (molecular formula C18H20ClN3O4S, MW 409.89 g/mol) for analytical method development and quality control.
The molecular framework of N-(3-chlorophenyl)-2-(2-oxo-5-(piperidin-1-ylsulfonyl)pyridin-1(2H)-yl)acetamide (C18H20ClN3O4S) is characterized by a flavonoid core, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures N-(3-chlorophenyl)-2-(2-oxo-5-(piperidin-1-ylsulfonyl)pyridin-1(2H)-yl)acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
