Chemical Structure

3-Methyl-4-nitropyridine <I>N</I>-oxide CAS 1074-98-2 chemical structure

Description

3-Methyl-4-nitropyridine <I>N</I>-oxide (CAS 1074-98-2), molecular formula C6H11N2O3 and molecular weight 159.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Methyl-4-nitropyridine <I>N</I>-oxide (C6H11N2O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

As a certified reference material (CRM), 3-Methyl-4-nitropyridine <I>N</I>-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.
