5-Bromo-3-methoxypyridin-2-amine, 97% CAS 42409-58-5

Description

The occurrence of 5-Bromo-3-methoxypyridin-2-amine, 97% is closely related to an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Bromo-3-methoxypyridin-2-amine, 97% (CAS 42409-58-5), molecular formula C6H7BrN2O and molecular weight 203.04 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Bromo-3-methoxypyridin-2-amine, 97% (C6H7BrN2O) 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. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
