Chemical Structure
Description
Pentafluoroethyl ethyl ketone (CAS 378-72-3) is a high-purity analytical reference standard with the molecular formula C5H5F5O and a molecular weight of 176.08 g/mol.
Based on its molecular formula C5H5F5O, Pentafluoroethyl ethyl ketone contains a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 176.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
CATO manufactures Pentafluoroethyl ethyl ketone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
