Chemical Structure
Description
The molecular framework of 1-Ethynyl-2-methyl-3-(trifluoromethyl)benzene (C10H7F3) 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. 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).
1-Ethynyl-2-methyl-3-(trifluoromethyl)benzene (CAS 2029239-28-7) is a high-purity analytical reference standard with the molecular formula C10H7F3 and a molecular weight of 184.16 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
