Description
CATO manufactures 5,7-Dibromoquinolin-8-yl 4-nitrobenzoate 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.
CATO supplies 5,7-Dibromoquinolin-8-yl 4-nitrobenzoate (CAS 4021-27-6), a certified reference material (molecular formula C16H8Br2N2O4, MW 452.05 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 5,7-Dibromoquinolin-8-yl 4-nitrobenzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 452.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
