Description
CATO manufactures 1,1'-(2,5-Dimethyl-1,4-phenylene)dipyrene 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.
1,1'-(2,5-Dimethyl-1,4-phenylene)dipyrene (CAS 1036404-84-8) is a high-purity analytical reference standard with the molecular formula C40H26 and a molecular weight of 506.63 g/mol.
Owing to a polycyclic aromatic system, 1,1'-(2,5-Dimethyl-1,4-phenylene)dipyrene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 506.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
