Chemical Structure
Description
CATO supplies 5-(((6-Methoxypyridin-3-yl)amino)methylene)-2,2-dimethyl-1,3-dioxane-4,6-dione (CAS 25063-69-8), a certified reference material (molecular formula C13H14N2O5, MW 278.26 g/mol) for analytical method development and quality control.
The molecular framework of 5-(((6-Methoxypyridin-3-yl)amino)methylene)-2,2-dimethyl-1,3-dioxane-4,6-dione (C13H14N2O5) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
