Chemical Structure
Description
2-Amino-3-bromo-5,6-dimethylpyridine (CAS 161091-49-2) is a high-purity analytical reference standard with the molecular formula C7H9BrN2 and a molecular weight of 201.06 g/mol.
2-Amino-3-bromo-5,6-dimethylpyridine (C7H9BrN2) contains a nitrile group, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 2-Amino-3-bromo-5,6-dimethylpyridine 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.
