Chemical Structure
Description
The occurrence of 4-(4-Bromostyryl)-N,N-diphenylaniline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-(4-Bromostyryl)-N,N-diphenylaniline (CAS 219987-44-7), a certified reference material (molecular formula C26H20BrN, MW 426.35 g/mol) for analytical method development and quality control.
4-(4-Bromostyryl)-N,N-diphenylaniline (C26H20BrN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 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.
