Chemical Structure
Description
5-Phenyl-10,15,20-tri(4-carboxyphenyl)porphine (CAS 142168-24-9) is a high-purity analytical reference standard with the molecular formula C47H30N4O6 and a molecular weight of 746.76 g/mol.
The molecular framework of 5-Phenyl-10,15,20-tri(4-carboxyphenyl)porphine (C47H30N4O6) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures 5-Phenyl-10,15,20-tri(4-carboxyphenyl)porphine 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.
