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-Tetra(4-methylphenyl)-21H,23H-porphine cobalt (CAS 19414-65-4) is a high-purity analytical reference standard with the molecular formula C50H42CoN4 and a molecular weight of 757.83 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5,10,15,20-Tetra(4-methylphenyl)-21H,23H-porphine cobalt is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 757.83 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), 5,10,15,20-Tetra(4-methylphenyl)-21H,23H-porphine cobalt 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.
