(2S,3R)-2-Amino-4,4,4-trifluoro-3-methylbutanoic acid CAS 409333-57-9

Description

The occurrence of (2S,3R)-2-Amino-4,4,4-trifluoro-3-methylbutanoic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2S,3R)-2-Amino-4,4,4-trifluoro-3-methylbutanoic acid (CAS 409333-57-9), molecular formula C5H8F3NO2 and molecular weight 171.12 g/mol, is a CATO reference standard with documented purity and traceability.

(2S,3R)-2-Amino-4,4,4-trifluoro-3-methylbutanoic acid (C5H8F3NO2) contains an amide group, a carboxylic acid 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. 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.
