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.
trans,trans-4-(3,4-Difluorophenyl)-4'-butyl-bicyclohexyl (CAS 82832-58-4), molecular formula C22H32F2 and molecular weight 334.49 g/mol, is a CATO reference standard with documented purity and traceability.
trans,trans-4-(3,4-Difluorophenyl)-4'-butyl-bicyclohexyl (C22H32F2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
