Chemical Structure
Description
The occurrence of Palladium tetrakis(4-carboxyphenyl)porphyrin is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Palladium tetrakis(4-carboxyphenyl)porphyrin (CAS 94288-44-5), molecular formula C48H28N4O8Pd and molecular weight 895.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Palladium tetrakis(4-carboxyphenyl)porphyrin (C48H28N4O8Pd) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 37.0, corresponding to approximately 37 ring(s) or double-bond equivalent(s). With a molecular weight of 895.18 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
