Chemical Structure

4-Chloro-N-cyclopropyl-2-fluorobenzenesulfonamide CAS 794572-98-8 chemical structure

Description

The occurrence of 4-Chloro-N-cyclopropyl-2-fluorobenzenesulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Chloro-N-cyclopropyl-2-fluorobenzenesulfonamide (CAS 794572-98-8), a certified reference material (molecular formula C9H9ClFNO2S, MW 249.69 g/mol) for analytical method development and quality control.

Structurally, 4-Chloro-N-cyclopropyl-2-fluorobenzenesulfonamide (C9H9ClFNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine 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 249.69 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 4-Chloro-N-cyclopropyl-2-fluorobenzenesulfonamide 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.
