5,5,5-Trifluoropentan-2-ol CAS 352-58-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,5,5-Trifluoropentan-2-ol.

5,5,5-Trifluoropentan-2-ol (CAS 352-58-9), molecular formula C5H9F3O and molecular weight 142.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, fluorine substitution, 5,5,5-Trifluoropentan-2-ol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.12 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.

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.

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.
