1,1,2,2-Tetrakis(4-(1H-pyrazol-3-yl)phenyl)ethene CAS 2845187-26-8

Description

The occurrence of 1,1,2,2-Tetrakis(4-(1H-pyrazol-3-yl)phenyl)ethene is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,1,2,2-Tetrakis(4-(1H-pyrazol-3-yl)phenyl)ethene (CAS 2845187-26-8), molecular formula C38H28N8 and molecular weight 596.68 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C38H28N8, 1,1,2,2-Tetrakis(4-(1H-pyrazol-3-yl)phenyl)ethene contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 596.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
