Chemical Structure
Description
(E)-4,5,5,5-tetrafluoro-4-(1,1,2,2,3,3,3-heptafluoropropoxy)pent-2-en-1-ol (CAS 261760-10-5) is a high-purity analytical reference standard with the molecular formula C8H5F11O2 and a molecular weight of 342.11 g/mol.
The molecular framework of (E)-4,5,5,5-tetrafluoro-4-(1,1,2,2,3,3,3-heptafluoropropoxy)pent-2-en-1-ol (C8H5F11O2) is characterized by a carboxylic acid group, 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.
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), (E)-4,5,5,5-tetrafluoro-4-(1,1,2,2,3,3,3-heptafluoropropoxy)pent-2-en-1-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
