Chemical Structure
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 nickel (CAS 58188-46-8) is a high-purity analytical reference standard with the molecular formula C50H42N4Ni and a molecular weight of 757.59 g/mol.
Structurally, 5,10,15,20-Tetra(4-methylphenyl)-21H,23H-porphine nickel (C50H42N4Ni) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 32.0, corresponding to approximately 32 ring(s) or double-bond equivalent(s). With a molecular weight of 757.59 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
