Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 238.25 g/mol gives Ethyl 5-(2-fluorophenyl)-5-oxopentanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 5-(2-fluorophenyl)-5-oxopentanoate (CAS 898753-35-0), molecular formula C13H15FO3 and molecular weight 238.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, Ethyl 5-(2-fluorophenyl)-5-oxopentanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.25 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.
