Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 183.25 g/mol gives 3-Methyl-2-(p-tolyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Methyl-2-(p-tolyl)pyridine (CAS 64291-96-9), a certified reference material (molecular formula C13H13N, MW 183.25 g/mol) for analytical method development and quality control.
The molecular framework of 3-Methyl-2-(p-tolyl)pyridine (C13H13N) 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.
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.
As a certified reference material (CRM), 3-Methyl-2-(p-tolyl)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.
