5,10,15,20-tetraphenyl-21<I>H</I>,23<I>H</I>-porphine cobalt(II) CAS 14172-90-8

Description

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.

5,10,15,20-tetraphenyl-21<I>H</I>,23<I>H</I>-porphine cobalt(II) (CAS 14172-90-8), molecular formula C44H74CoN4 and molecular weight 718.02 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5,10,15,20-tetraphenyl-21<I>H</I>,23<I>H</I>-porphine cobalt(II) (C44H74CoN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures 5,10,15,20-tetraphenyl-21<I>H</I>,23<I>H</I>-porphine cobalt(II) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
