Chemical Structure
Description
(R)-2-((tert-Butoxycarbonyl)amino)-4-fluoro-4-methylpentanoic acid (CAS 1447616-06-9), molecular formula C11H20FNO4 and molecular weight 249.28 g/mol, is a CATO reference standard with documented purity and traceability.
(R)-2-((tert-Butoxycarbonyl)amino)-4-fluoro-4-methylpentanoic acid (C11H20FNO4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
