Chemical Structure
Description
ethyl 6-bromo-2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxylate (CAS 894851-71-9) is a high-purity analytical reference standard with the molecular formula C11H17BrN2O3 and a molecular weight of 305.17 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, ethyl 6-bromo-2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
