Chemical Structure
Description
1-isopropenyl-3,5-di(trifluoromethyl)benzene (CAS 66875-48-7) is a high-purity analytical reference standard with the molecular formula C11H8F6 and a molecular weight of 254.17 g/mol.
Based on its molecular formula C11H8F6, 1-isopropenyl-3,5-di(trifluoromethyl)benzene contains fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 254.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
