Chemical Structure
Description
The occurrence of tert-Butyl 6-cyano-2-oxo-1,2-dihydropyridine-3-carboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
tert-Butyl 6-cyano-2-oxo-1,2-dihydropyridine-3-carboxylate (CAS 81450-70-6), molecular formula C11H12N2O3 and molecular weight 220.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl 6-cyano-2-oxo-1,2-dihydropyridine-3-carboxylate (C11H12N2O3) 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.
