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 Ethyl 3-Oxo-3,4-dihydropyrido[2,3-b]pyrazine-2-carboxylate.
Ethyl 3-Oxo-3,4-dihydropyrido[2,3-b]pyrazine-2-carboxylate (CAS 114097-17-5) is a high-purity analytical reference standard with the molecular formula C10H9N3O3 and a molecular weight of 219.20 g/mol.
The molecular framework of Ethyl 3-Oxo-3,4-dihydropyrido[2,3-b]pyrazine-2-carboxylate (C10H9N3O3) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Ethyl 3-Oxo-3,4-dihydropyrido[2,3-b]pyrazine-2-carboxylate 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.
