Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 356.29 g/mol gives Dimethylbis(2,3,4,5-tetrafluorophenyl)silane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dimethylbis(2,3,4,5-tetrafluorophenyl)silane (CAS 17167-02-1), molecular formula C14H8F8Si and molecular weight 356.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Dimethylbis(2,3,4,5-tetrafluorophenyl)silane (C14H8F8Si) is characterized by fluorine substitution, a polycyclic aromatic 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
