Description
CATO supplies 10-Bromo-10'-(2-naphthyl)-9,9'-bianthracene (CAS 1172087-81-8), a certified reference material (molecular formula C38H23Br, MW 559.49 g/mol) for analytical method development and quality control.
10-Bromo-10'-(2-naphthyl)-9,9'-bianthracene (C38H23Br) contains bromine substitution, a polycyclic aromatic system. 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.
CATO manufactures 10-Bromo-10'-(2-naphthyl)-9,9'-bianthracene 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.
