Description
As a certified reference material (CRM), [(4-Fluorophenyl)ethynyl]trimethylsilane 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.
[(4-Fluorophenyl)ethynyl]trimethylsilane (CAS 130995-12-9) is a high-purity analytical reference standard with the molecular formula C11H13FSi and a molecular weight of 192.30 g/mol.
[(4-Fluorophenyl)ethynyl]trimethylsilane (C11H13FSi) contains fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
