Chemical Structure
Description
The molecular framework of 3,5-Dimethyl-1-(1,1,2,2,2-pentafluoroethyl)benzene (C10H9F5) is characterized by 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3,5-Dimethyl-1-(1,1,2,2,2-pentafluoroethyl)benzene (CAS 1447671-64-8) is a high-purity analytical reference standard with the molecular formula C10H9F5 and a molecular weight of 224.17 g/mol.
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 3,5-Dimethyl-1-(1,1,2,2,2-pentafluoroethyl)benzene 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.
