(E)-Ethyl 3-(2-ethoxy-5-methylphenyl)-2,2-difluoro-3-(2-((2-(trifluoromethyl)phenyl)sulfonyl)hydrazono)propanoate CAS 2738683-65-1

Description

Compared with other compounds in its class, the molecular weight of 508.46 g/mol gives (E)-Ethyl 3-(2-ethoxy-5-methylphenyl)-2,2-difluoro-3-(2-((2-(trifluoromethyl)phenyl)sulfonyl)hydrazono)propanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E)-Ethyl 3-(2-ethoxy-5-methylphenyl)-2,2-difluoro-3-(2-((2-(trifluoromethyl)phenyl)sulfonyl)hydrazono)propanoate (CAS 2738683-65-1) is a high-purity analytical reference standard with the molecular formula C21H21F5N2O5S and a molecular weight of 508.46 g/mol.

(E)-Ethyl 3-(2-ethoxy-5-methylphenyl)-2,2-difluoro-3-(2-((2-(trifluoromethyl)phenyl)sulfonyl)hydrazono)propanoate (C21H21F5N2O5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).

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.
