Chemical Structure
Description
The occurrence of tert-butyl 4-(2-amino-2-oxo-ethyl)piperazine-1-carboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies tert-butyl 4-(2-amino-2-oxo-ethyl)piperazine-1-carboxylate (CAS 77278-70-7), a certified reference material (molecular formula C11H21N3O3, MW 243.30 g/mol) for analytical method development and quality control.
tert-butyl 4-(2-amino-2-oxo-ethyl)piperazine-1-carboxylate (C11H21N3O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
