Chemical Structure

4,4,5,5,5-Pentafluoropent-2-en-1-ol CAS 148757-93-1 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

4,4,5,5,5-Pentafluoropent-2-en-1-ol (CAS 148757-93-1), molecular formula C5H5F5O and molecular weight 176.08 g/mol, is a CATO reference standard with documented purity and traceability.

4,4,5,5,5-Pentafluoropent-2-en-1-ol (C5H5F5O) contains a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
