Chemical Structure
Description
(R)-2-((tert-Butoxycarbonyl)amino)-3,3-difluoropropanoic acid (C8H13F2NO4) contains an amide group, a carboxylic acid 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.
(R)-2-((tert-Butoxycarbonyl)amino)-3,3-difluoropropanoic acid (CAS 2349311-08-4) is a high-purity analytical reference standard with the molecular formula C8H13F2NO4 and a molecular weight of 225.19 g/mol.
