Chemical Structure
Description
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.
5-Bromo-3-methoxy-2-nitropyridine (CAS 152684-26-9) is a high-purity analytical reference standard with the molecular formula C6H5BrN2O3 and a molecular weight of 233.02 g/mol.
The molecular framework of 5-Bromo-3-methoxy-2-nitropyridine (C6H5BrN2O3) is characterized by an amide 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).
CATO manufactures 5-Bromo-3-methoxy-2-nitropyridine 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.
