Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Ethoxyfuro[3,4-b]pyridin-7(5H)-one (CAS 25230-60-8) is a high-purity analytical reference standard with the molecular formula C9H9NO3 and a molecular weight of 179.17 g/mol.
The molecular framework of 5-Ethoxyfuro[3,4-b]pyridin-7(5H)-one (C9H9NO3) 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).
CATO manufactures 5-Ethoxyfuro[3,4-b]pyridin-7(5H)-one 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.
