Chemical Structure

1-Fluoro-4-methyl-2-vinylbenzene CAS 698-12-4 chemical structure

Description

1-Fluoro-4-methyl-2-vinylbenzene (CAS 698-12-4) is a high-purity analytical reference standard with the molecular formula C9H9F and a molecular weight of 136.17 g/mol.

The molecular framework of 1-Fluoro-4-methyl-2-vinylbenzene (C9H9F) is characterized by fluorine substitution, an aromatic ring system. 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.

As a certified reference material (CRM), 1-Fluoro-4-methyl-2-vinylbenzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
