Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 234.12 g/mol gives Ethyl pentafluoropropionyl acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl pentafluoropropionyl acetate (CAS 663-35-4) is a high-purity analytical reference standard with the molecular formula C7H7F5O3 and a molecular weight of 234.12 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Ethyl pentafluoropropionyl acetate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
