tert-Butyl (S)-4-Bromo-2-(Boc-amino)butyrate (CAS 163210-89-7), molecular formula C13H24BrNO4 and molecular weight 338.24 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl (S)-4-Bromo-2-(Boc-amino)butyrate (C13H24BrNO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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.
