6-Butyl-5-(4-iodobenzyl)-2-methylpyrimidine-4-carbonitrile (CAS 138444-18-5), molecular formula C17H18IN3 and molecular weight 391.25 g/mol, is a CATO reference standard with documented purity and traceability.
6-Butyl-5-(4-iodobenzyl)-2-methylpyrimidine-4-carbonitrile (C17H18IN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 6-Butyl-5-(4-iodobenzyl)-2-methylpyrimidine-4-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
