Description

The occurrence of Ethyl 7-methoxy-4-oxo-4H-chromene-3-carboxylate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 7-methoxy-4-oxo-4H-chromene-3-carboxylate (CAS 93097-22-4) is a high-purity analytical reference standard with the molecular formula C13H12O5 and a molecular weight of 248.23 g/mol.

Ethyl 7-methoxy-4-oxo-4H-chromene-3-carboxylate (C13H12O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
