Chemical Structure
Description
The molecular framework of 1-ethoxy-1,1,2,2,2-pentafluoroethane 22052-81-9 Ethyl pentafluoroethyl ether (C4H5F5O) is characterized by a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1-ethoxy-1,1,2,2,2-pentafluoroethane 22052-81-9 Ethyl pentafluoroethyl ether (CAS 22052-81-9) is a high-purity analytical reference standard with the molecular formula C4H5F5O and a molecular weight of 164.07 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-ethoxy-1,1,2,2,2-pentafluoroethane 22052-81-9 Ethyl pentafluoroethyl ether meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
