Chemical Structure
Description
951892-19-6 4-(2,4-Difluorophenyl)-2-methyl-1-butene MFCD07775049 (C11H12F2) contains fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
951892-19-6 4-(2,4-Difluorophenyl)-2-methyl-1-butene MFCD07775049 (CAS 951892-19-6), molecular formula C11H12F2 and molecular weight 182.21 g/mol, is a CATO reference standard with documented purity and traceability.
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.
