Chemical Structure
Description
CATO supplies tert-Butyl 4-(((benzyloxy)carbonyl)amino)-2-fluorobenzoate (CAS 324788-98-9), a certified reference material (molecular formula C19H20FNO4, MW 345.36 g/mol) for analytical method development and quality control.
tert-Butyl 4-(((benzyloxy)carbonyl)amino)-2-fluorobenzoate (C19H20FNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
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.
