Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4,4',4'',4'''-([2,2'-Bi(1,3-dithiolylidene)]-4,4',5,5'-tetrayl)tetrabenzonitrile (CAS 1356336-67-8), molecular formula C34H16N4S4 and molecular weight 608.78 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 4,4',4'',4'''-([2,2'-Bi(1,3-dithiolylidene)]-4,4',5,5'-tetrayl)tetrabenzonitrile is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 608.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 4,4',4'',4'''-([2,2'-Bi(1,3-dithiolylidene)]-4,4',5,5'-tetrayl)tetrabenzonitrile 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.
