5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphyrin-Co CAS 14244-55-4

Description

The occurrence of 5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphyrin-Co is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphyrin-Co (CAS 14244-55-4), molecular formula C40H24CoN8 and molecular weight 675.61 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphyrin-Co is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 675.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
