5-Bromo-2-(ethylsulfonyl)pyridine CAS 223556-06-7

Description

Compared with other compounds in its class, the molecular weight of 250.11 g/mol gives 5-Bromo-2-(ethylsulfonyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-Bromo-2-(ethylsulfonyl)pyridine (CAS 223556-06-7), a certified reference material (molecular formula C7H8BrNO2S, MW 250.11 g/mol) for analytical method development and quality control.

The molecular framework of 5-Bromo-2-(ethylsulfonyl)pyridine (C7H8BrNO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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 5-Bromo-2-(ethylsulfonyl)pyridine 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.
