Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 398.89 g/mol gives 2,5-Diiodo-3-(trifluoromethyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,5-Diiodo-3-(trifluoromethyl)pyridine (CAS 1806353-75-2), molecular formula C6H2F3I2N and molecular weight 398.89 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,5-Diiodo-3-(trifluoromethyl)pyridine (C6H2F3I2N) is characterized by a nitrile group, fluorine/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).
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), 2,5-Diiodo-3-(trifluoromethyl)pyridine 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.
