Chemical Structure

2-Picoline N-oxide CAS 931-19-1 chemical structure

Description

As a certified reference material (CRM), 2-Picoline N-oxide 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 2-Picoline N-oxide (CAS 931-19-1), a certified reference material (molecular formula C6H7NO, MW 109.13 g/mol) for analytical method development and quality control.

The molecular framework of 2-Picoline N-oxide (C6H7NO) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
