Chemical Structure

5-Bromo-2-chloro-3-(methylsulfonyl)pyridine CAS 887308-14-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 270.53 g/mol gives 5-Bromo-2-chloro-3-(methylsulfonyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Bromo-2-chloro-3-(methylsulfonyl)pyridine (CAS 887308-14-7) is a high-purity analytical reference standard with the molecular formula C6H5BrClNO2S and a molecular weight of 270.53 g/mol.

5-Bromo-2-chloro-3-(methylsulfonyl)pyridine (C6H5BrClNO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. 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. 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 5-Bromo-2-chloro-3-(methylsulfonyl)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.
