Chemical Structure
Description
5-bromo-2-hydroxy-3-nitropyridine (CAS 15862-34-7), molecular formula C5H9BrN2O3 and molecular weight 225.04 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H9BrN2O3, 5-bromo-2-hydroxy-3-nitropyridine contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 225.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-hydroxy-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.
