Chemical Structure
Description
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.
1-(1,1-Difluoroethyl)-3-(trifluoromethyl)benzene (CAS 1071212-33-3), molecular formula C9H7F5 and molecular weight 210.14 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H7F5, 1-(1,1-Difluoroethyl)-3-(trifluoromethyl)benzene contains fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 210.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
