Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-bromo-5-chloro-2-iodopyridine.
CATO supplies 4-bromo-5-chloro-2-iodopyridine (CAS 1805015-33-1), a certified reference material (molecular formula C5H2BrClIN, MW 318.34 g/mol) for analytical method development and quality control.
The molecular framework of 4-bromo-5-chloro-2-iodopyridine (C5H2BrClIN) is characterized by a nitrile group, chlorine/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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-5-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.
