1-ethynyl-3-fluoro-benzene 1-ethynyl-3-fluorobenzene 2561-17-3 3'-fluorophenyl acetylene 3-fluorophenylacetylene 3-fluorophenylacetylene 98% 3-fluorophenylacetylene98% benzene, 1-ethynyl-3-fluoro- benzene, 1-ethynyl-3-fluoro- (7ci, 8ci, 9ci) (CAS 2561-17-3) is a high-purity analytical reference standard with the molecular formula C8H11F and a molecular weight of 126.17 g/mol.

The molecular framework of 1-ethynyl-3-fluoro-benzene 1-ethynyl-3-fluorobenzene 2561-17-3 3'-fluorophenyl acetylene 3-fluorophenylacetylene 3-fluorophenylacetylene 98% 3-fluorophenylacetylene98% benzene, 1-ethynyl-3-fluoro- benzene, 1-ethynyl-3-fluoro- (7ci, 8ci, 9ci) (C8H11F) is characterized by fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.

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.
