Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 148.18 g/mol gives 1-(1,3-Butadien-2-Yl)-4-Fluorobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(1,3-Butadien-2-Yl)-4-Fluorobenzene (CAS 128233-08-9) is a high-purity analytical reference standard with the molecular formula C10H9F and a molecular weight of 148.18 g/mol.
The molecular framework of 1-(1,3-Butadien-2-Yl)-4-Fluorobenzene (C10H9F) is characterized by fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
