Compared with other compounds in its class, the molecular weight of 238.15 g/mol gives 2’-(Pentafluoroethyl)acetophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2’-(Pentafluoroethyl)acetophenone (CAS 133391-51-2) is a high-purity analytical reference standard with the molecular formula C10H7F5O and a molecular weight of 238.15 g/mol.
The molecular framework of 2’-(Pentafluoroethyl)acetophenone (C10H7F5O) is characterized by a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures 2’-(Pentafluoroethyl)acetophenone 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.
