Chemical Structure

n-Ethyl-2,5-difluorobenzene-1-sulfonamide CAS 898074-77-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 221.22 g/mol gives n-Ethyl-2,5-difluorobenzene-1-sulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies n-Ethyl-2,5-difluorobenzene-1-sulfonamide (CAS 898074-77-6), a certified reference material (molecular formula C8H9F2NO2S, MW 221.22 g/mol) for analytical method development and quality control.

n-Ethyl-2,5-difluorobenzene-1-sulfonamide (C8H9F2NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-Ethyl-2,5-difluorobenzene-1-sulfonamide 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.
