Chemical Structure

3-{[(tert-butoxy)carbonyl]amino}-4-fluorobenzoic acid CAS 1184472-44-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 255.24 g/mol gives 3-{[(tert-butoxy)carbonyl]amino}-4-fluorobenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-{[(tert-butoxy)carbonyl]amino}-4-fluorobenzoic acid (CAS 1184472-44-3), a certified reference material (molecular formula C12H14FNO4, MW 255.24 g/mol) for analytical method development and quality control.

3-{[(tert-butoxy)carbonyl]amino}-4-fluorobenzoic acid (C12H14FNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
