Chemical Structure

5-methylpyridine-2-carboxamide CAS 20970-77-8 chemical structure

Description

CATO supplies 5-methylpyridine-2-carboxamide (CAS 20970-77-8), a certified reference material (molecular formula C7H8N2O, MW 136.15 g/mol) for analytical method development and quality control.

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 5-methylpyridine-2-carboxamide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 5-methylpyridine-2-carboxamide 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.
