Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-5-bromobenzoic acid (CAS 1536367-22-2), a certified reference material (molecular formula C22H16BrNO4, MW 438.27 g/mol) for analytical method development and quality control.
3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-5-bromobenzoic acid (C22H16BrNO4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
