Chemical Structure

3-((3,4-Dichlorobenzyl)sulfonyl)-N-(2,4-difluorophenyl)thiophene-2-carboxamide CAS 251097-76-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 462.32 g/mol gives 3-((3,4-Dichlorobenzyl)sulfonyl)-N-(2,4-difluorophenyl)thiophene-2-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-((3,4-Dichlorobenzyl)sulfonyl)-N-(2,4-difluorophenyl)thiophene-2-carboxamide (CAS 251097-76-4), a certified reference material (molecular formula C18H11Cl2F2NO3S2, MW 462.32 g/mol) for analytical method development and quality control.

3-((3,4-Dichlorobenzyl)sulfonyl)-N-(2,4-difluorophenyl)thiophene-2-carboxamide (C18H11Cl2F2NO3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.

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.
