Chemical Structure
Description
The molecular framework of N,N'-(Methylenebis(4,1-phenylene))bis(1-(pyridin-2-yl)methanimine) (C25H20N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
N,N'-(Methylenebis(4,1-phenylene))bis(1-(pyridin-2-yl)methanimine) (CAS 192586-42-8) is a high-purity analytical reference standard with the molecular formula C25H20N4 and a molecular weight of 376.45 g/mol.
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), N,N'-(Methylenebis(4,1-phenylene))bis(1-(pyridin-2-yl)methanimine) 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.
