Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 240.30 g/mol gives ethyl 6-methyl-4-oxo-chromene-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
ethyl 6-methyl-4-oxo-chromene-2-carboxylate (CAS 38322-65-5) is a high-purity analytical reference standard with the molecular formula C13H20O4 and a molecular weight of 240.30 g/mol.
The molecular framework of ethyl 6-methyl-4-oxo-chromene-2-carboxylate (C13H20O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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 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.
