Chemical Structure
Description
CATO supplies (2S,3R)-2-((tert-Butoxycarbonyl)amino)-3-hydroxy-4,4-dimethylpentanoic acid (CAS 1631082-57-9), a certified reference material (molecular formula C11H20FNO5, MW 265.28 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H20FNO5, (2S,3R)-2-((tert-Butoxycarbonyl)amino)-3-hydroxy-4,4-dimethylpentanoic acid contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 265.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
