Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 637.02 g/mol gives Magnesium(II) meso-tetraphenylporphine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Magnesium(II) meso-tetraphenylporphine (CAS 14640-21-2) is a high-purity analytical reference standard with the molecular formula C44H28MgN4 and a molecular weight of 637.02 g/mol.
The molecular framework of Magnesium(II) meso-tetraphenylporphine (C44H28MgN4) 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.
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.
