Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (S)-2-((tert-butoxycarbonyl)amino)-4,4,4-trifluoro-3,3-dimethylbutanoic acid (CAS 2242426-52-2), a certified reference material (molecular formula C11H18F3NO4, MW 285.26 g/mol) for analytical method development and quality control.
(S)-2-((tert-butoxycarbonyl)amino)-4,4,4-trifluoro-3,3-dimethylbutanoic acid (C11H18F3NO4) 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.
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.
