Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 244.03 g/mol gives 5-Iodo-2-methylnicotinonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Iodo-2-methylnicotinonitrile (CAS 1346533-56-9), molecular formula C7H5IN2 and molecular weight 244.03 g/mol, is a CATO reference standard with documented purity and traceability.
5-Iodo-2-methylnicotinonitrile (C7H5IN2) contains a nitrile group, iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 5-Iodo-2-methylnicotinonitrile 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.
