Chemical Structure

3,5-Dibromo-4-iodopyridine CAS 1214383-75-1 chemical structure

Description

The occurrence of 3,5-Dibromo-4-iodopyridine is closely related to a nitrile group, bromine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,5-Dibromo-4-iodopyridine (CAS 1214383-75-1), 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-4-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. 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.

As a certified reference material (CRM), 3,5-Dibromo-4-iodopyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
