4-Methylaminopyridine CAS 3731-53-1 chemical structure

Description

As a certified reference material (CRM), 4-Methylaminopyridine 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.

CATO supplies 4-Methylaminopyridine (CAS 3731-53-1), a certified reference material (molecular formula C6H8N2, MW 108.14 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H8N2, 4-Methylaminopyridine contains a nitrile group, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 108.14 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.
