Chemical Structure

N-methyl-N-nitrosopyridin-4-amine CAS 16219-99-1 chemical structure

Description

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

CATO supplies N-methyl-N-nitrosopyridin-4-amine (CAS 16219-99-1), a certified reference material (molecular formula C6H7N3O, MW 137.14 g/mol) for analytical method development and quality control.

The molecular framework of N-methyl-N-nitrosopyridin-4-amine (C6H7N3O) 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).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
