Chemical Structure

5,10,15,20-Tetrakis(2-methylphenyl)porphyrin CAS 37083-40-2 chemical structure

Description

5,10,15,20-Tetrakis(2-methylphenyl)porphyrin (CAS 37083-40-2) is a high-purity analytical reference standard with the molecular formula C48H38N4 and a molecular weight of 670.84 g/mol.

Structurally, 5,10,15,20-Tetrakis(2-methylphenyl)porphyrin (C48H38N4) 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 670.84 g/mol, it falls into the high-molecular-weight range. 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.

As a certified reference material (CRM), 5,10,15,20-Tetrakis(2-methylphenyl)porphyrin 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.
