Chemical Structure
Description
The molecular framework of Ethyl 6-bromo-8-methoxy-2H-chromene-3-carboxylate (C13H13BrO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
Ethyl 6-bromo-8-methoxy-2H-chromene-3-carboxylate (CAS 885271-21-6), molecular formula C13H13BrO4 and molecular weight 313.14 g/mol, is a CATO reference standard with documented purity and traceability.
