Description
CATO manufactures 3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-bromobenzoic acid 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.
3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-bromobenzoic acid (CAS 1696643-67-0), molecular formula C22H16BrNO4 and molecular weight 438.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-bromobenzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 438.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
