Chemical Structure

5,10,15,20-Tetra(4-ethynylphenyl)porphyrin CAS 160240-15-3 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5,10,15,20-Tetra(4-ethynylphenyl)porphyrin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 710.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 supplies 5,10,15,20-Tetra(4-ethynylphenyl)porphyrin (CAS 160240-15-3), a certified reference material (molecular formula C52H30N4, MW 710.82 g/mol) for analytical method development and quality control.

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.
