Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Bis(2-hydroxy-3-biphenylcarboxylato)copper (CAS 18918-16-6) is a high-purity analytical reference standard with the molecular formula C26H18CuO6 and a molecular weight of 489.96 g/mol.
Bis(2-hydroxy-3-biphenylcarboxylato)copper (C26H18CuO6) contains a steroid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Bis(2-hydroxy-3-biphenylcarboxylato)copper 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.
