Zn(II) meso-Tetra (N-methyl-4-pyridyl) Porphine Tetrachloride CAS 28850-44-4

Description

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.

Zn(II) meso-Tetra (N-methyl-4-pyridyl) Porphine Tetrachloride (CAS 28850-44-4), molecular formula C44H46N8ZnCl and molecular weight 787.74 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Zn(II) meso-Tetra (N-methyl-4-pyridyl) Porphine Tetrachloride (C44H46N8ZnCl) contains a salt form, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 25.5, corresponding to approximately 25 ring(s) or double-bond equivalent(s). With a molecular weight of 787.74 g/mol, it falls into the high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
