Chemical Structure
Description
The occurrence of 3-Bromo-4-chloro-2-iodopyridine is closely related to a nitrile group, chlorine/bromine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Bromo-4-chloro-2-iodopyridine (CAS 1807003-79-7) is a high-purity analytical reference standard with the molecular formula C5H2BrClIN and a molecular weight of 318.34 g/mol.
Owing to a nitrile group, chlorine/bromine/iodine substitution, 3-Bromo-4-chloro-2-iodopyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-Bromo-4-chloro-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.
