Chemical Structure

2,6-Di(pyridin-4-yl)naphthalene CAS 950520-39-5 chemical structure

Description

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.

2,6-Di(pyridin-4-yl)naphthalene (CAS 950520-39-5) is a high-purity analytical reference standard with the molecular formula C20H14N2 and a molecular weight of 282.34 g/mol.

The molecular framework of 2,6-Di(pyridin-4-yl)naphthalene (C20H14N2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 2,6-Di(pyridin-4-yl)naphthalene 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.
