CATO supplies 2-Fluorophenylacetylene 1-Ethynyl-2-fluorobenzene 2'-fluorophenyl acetylene 1-ethynyl-2-fluoro-benzene 2'-fluorophenylacetylene 766-49-4 (CAS 766-49-4), a certified reference material (molecular formula C8H11F, MW 126.17 g/mol) for analytical method development and quality control.
Structurally, 2-Fluorophenylacetylene 1-Ethynyl-2-fluorobenzene 2'-fluorophenyl acetylene 1-ethynyl-2-fluoro-benzene 2'-fluorophenylacetylene 766-49-4 (C8H11F) contains fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 126.17 g/mol, it falls into the low-molecular-weight range. 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.
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.
