Chemical Structure

5,15-Di-p-tolylporphyrin CAS 128374-05-0 chemical structure

Description

As a certified reference material (CRM), 5,15-Di-p-tolylporphyrin meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies 5,15-Di-p-tolylporphyrin (CAS 128374-05-0), a certified reference material (molecular formula C34H26N4, MW 490.60 g/mol) for analytical method development and quality control.

The molecular framework of 5,15-Di-p-tolylporphyrin (C34H26N4) 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.

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.
