3,3-Bis(1-Methylethyl)-1-(2,2,2-Trifluoroethyl)-2,4-Azetidinedione CAS 56519-50-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3,3-Bis(1-Methylethyl)-1-(2,2,2-Trifluoroethyl)-2,4-Azetidinedione (CAS 56519-50-7) is a high-purity analytical reference standard with the molecular formula C11H16F3NO2 and a molecular weight of 251.25 g/mol.

3,3-Bis(1-Methylethyl)-1-(2,2,2-Trifluoroethyl)-2,4-Azetidinedione (C11H16F3NO2) contains an amide group, a carboxylic acid group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
