Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,1'-(9,9-Dimethyl-9H-fluorene-2,7-diyl)bis(1H-imidazole) (CAS 1588929-66-1), molecular formula C21H18N4 and molecular weight 326.39 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H18N4, 1,1'-(9,9-Dimethyl-9H-fluorene-2,7-diyl)bis(1H-imidazole) contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 326.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
CATO manufactures 1,1'-(9,9-Dimethyl-9H-fluorene-2,7-diyl)bis(1H-imidazole) 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.
