Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 286.15 g/mol gives 3-Bromo-8-(methylsulfonyl)quinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-8-(methylsulfonyl)quinoline (CAS 1956385-35-5) is a high-purity analytical reference standard with the molecular formula C10H8BrNO2S and a molecular weight of 286.15 g/mol.
The molecular framework of 3-Bromo-8-(methylsulfonyl)quinoline (C10H8BrNO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 3-Bromo-8-(methylsulfonyl)quinoline 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.
