Description
CATO manufactures Ethyl 5,6,7-trifluoro-4-oxo-1,4-dihydroquinoline-3-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.
Ethyl 5,6,7-trifluoro-4-oxo-1,4-dihydroquinoline-3-carboxylate (CAS 836619-82-0) is a high-purity analytical reference standard with the molecular formula C12H8F3NO3 and a molecular weight of 271.19 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Ethyl 5,6,7-trifluoro-4-oxo-1,4-dihydroquinoline-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
