Chemical Structure
Description
2-(4-Fluoro-3-iodobenzylidene)malononitrile (CAS 2168948-73-8), molecular formula C10H4FIN2 and molecular weight 298.06 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H4FIN2, 2-(4-Fluoro-3-iodobenzylidene)malononitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 298.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(4-Fluoro-3-iodobenzylidene)malononitrile 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.
