Chemical Structure
Description
The occurrence of 1-Fluoro-4-(2-phenylethynyl)benzene is closely related to fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-Fluoro-4-(2-phenylethynyl)benzene (CAS 405-29-8), a certified reference material (molecular formula C14H9F, MW 196.22 g/mol) for analytical method development and quality control.
1-Fluoro-4-(2-phenylethynyl)benzene (C14H9F) contains fluorine substitution, a polycyclic aromatic 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
