Chemical Structure
Description
The occurrence of 6-bromo-2-[(E)-2-[4-(trifluoromethoxy)phenyl]ethenyl]quinoline-4-carboxylic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-bromo-2-[(E)-2-[4-(trifluoromethoxy)phenyl]ethenyl]quinoline-4-carboxylic acid (CAS 926199-81-7), molecular formula C19H11BrF3NO3 and molecular weight 438.19 g/mol, is a CATO reference standard with documented purity and traceability.
6-bromo-2-[(E)-2-[4-(trifluoromethoxy)phenyl]ethenyl]quinoline-4-carboxylic acid (C19H11BrF3NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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 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.
As a certified reference material (CRM), 6-bromo-2-[(E)-2-[4-(trifluoromethoxy)phenyl]ethenyl]quinoline-4-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
