Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,6-Dimethylpyridine-3,5-dicarboxylic acid diethyl ester.
CATO supplies 2,6-Dimethylpyridine-3,5-dicarboxylic acid diethyl ester (CAS 1149-24-2), a certified reference material (molecular formula C13H23NO4, MW 257.33 g/mol) for analytical method development and quality control.
2,6-Dimethylpyridine-3,5-dicarboxylic acid diethyl ester (C13H23NO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
