Chemical Structure
Description
The occurrence of 2,4,6-Tris-(4-pyridyl)pyridine 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.
2,4,6-Tris-(4-pyridyl)pyridine (CAS 113919-79-2) is a high-purity analytical reference standard with the molecular formula C20H14N4 and a molecular weight of 310.35 g/mol.
Based on its molecular formula C20H14N4, 2,4,6-Tris-(4-pyridyl)pyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 310.35 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,4,6-Tris-(4-pyridyl)pyridine 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.
