4-Bromo-N-(4-(phenylethynyl)phenyl)benzenesulfonamide CAS 439097-33-3

Description

The occurrence of 4-Bromo-N-(4-(phenylethynyl)phenyl)benzenesulfonamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Bromo-N-(4-(phenylethynyl)phenyl)benzenesulfonamide (CAS 439097-33-3) is a high-purity analytical reference standard with the molecular formula C20H14BrNO2S and a molecular weight of 412.30 g/mol.

4-Bromo-N-(4-(phenylethynyl)phenyl)benzenesulfonamide (C20H14BrNO2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine 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.
