Chemical Structure
Description
Ethyl 5-ethyl-2,4-dihydroxy-6-methylnicotinate (CAS 172470-04-1), molecular formula C11H15NO4 and molecular weight 225.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 5-ethyl-2,4-dihydroxy-6-methylnicotinate (C11H15NO4) 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. 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.
