Chemical Structure

6-Ethyl-5-methylnicotinonitrile CAS 110253-41-3 chemical structure

Description

CATO supplies 6-Ethyl-5-methylnicotinonitrile (CAS 110253-41-3), a certified reference material (molecular formula C9H10N2, MW 146.19 g/mol) for analytical method development and quality control.

The molecular framework of 6-Ethyl-5-methylnicotinonitrile (C9H10N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 6-Ethyl-5-methylnicotinonitrile 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.
