Chemical Structure
Description
3,5-Dibromo-2-iodopyridine (CAS 436799-34-7), molecular formula C5H2Br2IN and molecular weight 362.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,5-Dibromo-2-iodopyridine (C5H2Br2IN) 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 3,5-Dibromo-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.
