1,1-Dicyano-2-(pyridine-4-yl)ethylene CAS 63080-75-1

Description

The occurrence of 1,1-Dicyano-2-(pyridine-4-yl)ethylene 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-Dicyano-2-(pyridine-4-yl)ethylene (CAS 63080-75-1), molecular formula C9H5N3 and molecular weight 155.16 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H5N3, 1,1-Dicyano-2-(pyridine-4-yl)ethylene contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 155.16 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.
