Chemical Structure

3,4-Diiodopyridine CAS 83674-72-0 chemical structure

Description

The molecular framework of 3,4-Diiodopyridine (C5H3I2N) is characterized by a nitrile group, 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).

3,4-Diiodopyridine (CAS 83674-72-0) is a high-purity analytical reference standard with the molecular formula C5H3I2N and a molecular weight of 330.89 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 3,4-Diiodopyridine 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.
