Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 775.82 g/mol gives Cu(II) meso-Tetra(N-methyl-4-pyridyl) porphine tetrachloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Cu(II) meso-Tetra(N-methyl-4-pyridyl) porphine tetrachloride (CAS 79407-87-7), molecular formula C44H36CuN8Cl and molecular weight 775.82 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Cu(II) meso-Tetra(N-methyl-4-pyridyl) porphine tetrachloride (C44H36CuN8Cl) is characterized by a salt form, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
