Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-5-bromo-3-methylbenzoic acid (CAS 2243512-07-2) is a high-purity analytical reference standard with the molecular formula C23H18BrNO4 and a molecular weight of 452.30 g/mol.
2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-5-bromo-3-methylbenzoic acid (C23H18BrNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
As a certified reference material (CRM), 2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-5-bromo-3-methylbenzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
