Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,10,15,20-Tetra(4-methylphenyl)-21h,23h-porphine copper.
5,10,15,20-Tetra(4-methylphenyl)-21h,23h-porphine copper (CAS 19414-66-5), molecular formula C48H38N4Cu and molecular weight 734.41 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5,10,15,20-Tetra(4-methylphenyl)-21h,23h-porphine copper (C48H38N4Cu) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 32.0, corresponding to approximately 32 ring(s) or double-bond equivalent(s). With a molecular weight of 734.41 g/mol, it falls into the high-molecular-weight range. 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.
