Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Butyldimethyl(2,3,5,6-tetrafluorophenyl)silane (CAS 17167-03-2), molecular formula C12H16F4Si and molecular weight 264.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Butyldimethyl(2,3,5,6-tetrafluorophenyl)silane (C12H16F4Si) is characterized by fluorine substitution. 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.
As a certified reference material (CRM), Butyldimethyl(2,3,5,6-tetrafluorophenyl)silane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
