((4-((4-Fluorophenyl)ethynyl)phenyl)ethynyl)trimethylsilane (CAS 910467-79-7), molecular formula C19H17FSi and molecular weight 292.42 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine substitution, a polycyclic aromatic system, ((4-((4-Fluorophenyl)ethynyl)phenyl)ethynyl)trimethylsilane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures ((4-((4-Fluorophenyl)ethynyl)phenyl)ethynyl)trimethylsilane 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.
