2-(((Benzyloxy)carbonyl)amino)-3,3,3-trifluoro-2-methylpropanoic acid CAS 139520-43-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 291.22 g/mol gives 2-(((Benzyloxy)carbonyl)amino)-3,3,3-trifluoro-2-methylpropanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(((Benzyloxy)carbonyl)amino)-3,3,3-trifluoro-2-methylpropanoic acid (CAS 139520-43-7) is a high-purity analytical reference standard with the molecular formula C12H12F3NO4 and a molecular weight of 291.22 g/mol.

2-(((Benzyloxy)carbonyl)amino)-3,3,3-trifluoro-2-methylpropanoic acid (C12H12F3NO4) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
