Chemical Structure
Description
1-Ethyl-2-methyl-6-oxo-1,6-dihydropyridine-3-carboxylic acid (CAS 1823441-24-2), molecular formula C9H11NO3 and molecular weight 181.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Ethyl-2-methyl-6-oxo-1,6-dihydropyridine-3-carboxylic acid (C9H11NO3) 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.
CATO manufactures 1-Ethyl-2-methyl-6-oxo-1,6-dihydropyridine-3-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
