Chemical Structure

3,6-Diiodopicolinonitrile CAS 827616-53-5 chemical structure

Description

The occurrence of 3,6-Diiodopicolinonitrile is closely related to a nitrile group, iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3,6-Diiodopicolinonitrile (CAS 827616-53-5), a certified reference material (molecular formula C6H2I2N2, MW 355.90 g/mol) for analytical method development and quality control.

The molecular framework of 3,6-Diiodopicolinonitrile (C6H2I2N2) is characterized by a nitrile group, iodine substitution, an aromatic ring system. 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), 3,6-Diiodopicolinonitrile 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.
