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.
CATO supplies 4-(5,5-Dimethyl-1,3-dioxan-2-yl)-1-(4-(trifluoromethyl)phenyl)butan-1-one (CAS 898786-65-7), a certified reference material (molecular formula C17H21F3O3, MW 330.34 g/mol) for analytical method development and quality control.
4-(5,5-Dimethyl-1,3-dioxan-2-yl)-1-(4-(trifluoromethyl)phenyl)butan-1-one (C17H21F3O3) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
