Description
Compared with other compounds in its class, the molecular weight of 275.10 g/mol gives 5-Bromo-2-isobutoxy-3-nitropyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Bromo-2-isobutoxy-3-nitropyridine (CAS 1250043-16-3), a certified reference material (molecular formula C9H11BrN2O3, MW 275.10 g/mol) for analytical method development and quality control.
5-Bromo-2-isobutoxy-3-nitropyridine (C9H11BrN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, 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. 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 5-Bromo-2-isobutoxy-3-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.
