Chemical Structure
Description
The occurrence of 4-Bromo-2-iodopyridine is closely related to a nitrile group, bromine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-2-iodopyridine (CAS 100523-83-9) is a high-purity analytical reference standard with the molecular formula C5H3BrIN and a molecular weight of 283.89 g/mol.
The molecular framework of 4-Bromo-2-iodopyridine (C5H3BrIN) is characterized by a nitrile group, bromine/iodine substitution. 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.
CATO manufactures 4-Bromo-2-iodopyridine 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.
