Chemical Structure
Description
The occurrence of 2,2'-(Butane-1,4-diylbis(sulfanediyl))bis(N-(2-bromophenyl)acetamide) 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.
CATO supplies 2,2'-(Butane-1,4-diylbis(sulfanediyl))bis(N-(2-bromophenyl)acetamide) (CAS 301194-28-5), a certified reference material (molecular formula C20H22Br2N2O2S2, MW 546.34 g/mol) for analytical method development and quality control.
2,2'-(Butane-1,4-diylbis(sulfanediyl))bis(N-(2-bromophenyl)acetamide) (C20H22Br2N2O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, 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.
As a certified reference material (CRM), 2,2'-(Butane-1,4-diylbis(sulfanediyl))bis(N-(2-bromophenyl)acetamide) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
