Chemical Structure
Description
Copper(II)-4,4,4,4-phthalocyanine tetracarboxylic acid (CAS 16337-64-7), molecular formula C36H12CuN8O8H and molecular weight 749.09 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C36H12CuN8O8H, Copper(II)-4,4,4,4-phthalocyanine tetracarboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 749.09 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
