5,10,15,20-Tetrakis[4-[2-(trimethylsilyl)ethynyl]phenyl]-21H,23H-porphine CAS 145362-97-6

Description

As a certified reference material (CRM), 5,10,15,20-Tetrakis[4-[2-(trimethylsilyl)ethynyl]phenyl]-21H,23H-porphine 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.

5,10,15,20-Tetrakis[4-[2-(trimethylsilyl)ethynyl]phenyl]-21H,23H-porphine (CAS 145362-97-6), molecular formula C64H62N4Si4 and molecular weight 999.55 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C64H62N4Si4, 5,10,15,20-Tetrakis[4-[2-(trimethylsilyl)ethynyl]phenyl]-21H,23H-porphine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 999.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
