Chemical Structure
Description
2-Fluoro-N-(isoxazolo[5,4-b]pyridin-3-yl)benzamide (CAS 1021113-39-2), molecular formula C13H8FN3O2 and molecular weight 257.22 g/mol, is a CATO reference standard with documented purity and traceability.
2-Fluoro-N-(isoxazolo[5,4-b]pyridin-3-yl)benzamide (C13H8FN3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 2-Fluoro-N-(isoxazolo[5,4-b]pyridin-3-yl)benzamide 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.
