2,3,7,8,12,13,17,18-octaethyl-21<I>H</I>,23<I>H</I>-cobalt porphyrin(II) CAS 17632-19-8

Description

As a certified reference material (CRM), 2,3,7,8,12,13,17,18-octaethyl-21<I>H</I>,23<I>H</I>-cobalt porphyrin(II) 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.

2,3,7,8,12,13,17,18-octaethyl-21<I>H</I>,23<I>H</I>-cobalt porphyrin(II) (CAS 17632-19-8) is a high-purity analytical reference standard with the molecular formula C36H66CoN4 and a molecular weight of 613.87 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2,3,7,8,12,13,17,18-octaethyl-21<I>H</I>,23<I>H</I>-cobalt porphyrin(II) is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 613.87 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).

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.
