Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 200.03 g/mol gives 3-Acetyl-5-bromopyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Acetyl-5-bromopyridine (CAS 38940-62-4), a certified reference material (molecular formula C7H6BrNO, MW 200.03 g/mol) for analytical method development and quality control.
The molecular framework of 3-Acetyl-5-bromopyridine (C7H6BrNO) is characterized by an amide 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. 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-Acetyl-5-bromopyridine 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.
