Chemical Structure
Description
Owing to fluorine substitution, an aromatic ring system, ((3-Fluorophenyl)ethynyl)trimethylsilane is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 192.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
((3-Fluorophenyl)ethynyl)trimethylsilane (CAS 40230-96-4), molecular formula C11H13FSi and molecular weight 192.30 g/mol, is a CATO reference standard with documented purity and traceability.
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 ((3-Fluorophenyl)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.
