Chemical Structure

2,2-Difluoro-2-(3-(trifluoromethyl)phenoxy)-N-(4-(trifluoromethyl)phenyl)acetamide CAS 338792-23-7 chemical structure

Description

The occurrence of 2,2-Difluoro-2-(3-(trifluoromethyl)phenoxy)-N-(4-(trifluoromethyl)phenyl)acetamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,2-Difluoro-2-(3-(trifluoromethyl)phenoxy)-N-(4-(trifluoromethyl)phenyl)acetamide (CAS 338792-23-7), molecular formula C16H9F8NO2 and molecular weight 399.24 g/mol, is a CATO reference standard with documented purity and traceability.

2,2-Difluoro-2-(3-(trifluoromethyl)phenoxy)-N-(4-(trifluoromethyl)phenyl)acetamide (C16H9F8NO2) contains a nitrogen-containing heterocyclic scaffold, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
