Chemical Structure
Description
The molecular framework of Trimethyl((4-(trifluoromethoxy)phenyl)ethynyl)silane (C12H13F3OSi) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Trimethyl((4-(trifluoromethoxy)phenyl)ethynyl)silane (CAS 239104-48-4), molecular formula C12H13F3OSi and molecular weight 258.31 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Trimethyl((4-(trifluoromethoxy)phenyl)ethynyl)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.
