Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 134.15 g/mol gives 4-Ethynyl-2-fluoro-1-methylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Ethynyl-2-fluoro-1-methylbenzene (CAS 145069-53-0), a certified reference material (molecular formula C9H7F, MW 134.15 g/mol) for analytical method development and quality control.
The molecular framework of 4-Ethynyl-2-fluoro-1-methylbenzene (C9H7F) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-Ethynyl-2-fluoro-1-methylbenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
