Chemical Structure
Description
The occurrence of N-(4-Bromophenyl)-2,2-diphenylacetamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(4-Bromophenyl)-2,2-diphenylacetamide (CAS 70481-06-0), molecular formula C20H16BrNO and molecular weight 366.25 g/mol, is a CATO reference standard with documented purity and traceability.
N-(4-Bromophenyl)-2,2-diphenylacetamide (C20H16BrNO) contains a steroid core, an amide 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; 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.
CATO manufactures N-(4-Bromophenyl)-2,2-diphenylacetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
