Chemical Structure

5,10,15,20-Tetrakis(4-(pyridin-4-yl)phenyl)porphyrin CAS 1375257-01-4 chemical structure

Description

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.

5,10,15,20-Tetrakis(4-(pyridin-4-yl)phenyl)porphyrin (CAS 1375257-01-4) is a high-purity analytical reference standard with the molecular formula C64H42N8 and a molecular weight of 923.07 g/mol.

The molecular framework of 5,10,15,20-Tetrakis(4-(pyridin-4-yl)phenyl)porphyrin (C64H42N8) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).

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.
