Chemical Structure
Description
The occurrence of tert-Butyl 4-(3-methoxyquinoxalin-2-yl)piperazine-1-carboxylate is closely related to a steroid core, 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-(3-methoxyquinoxalin-2-yl)piperazine-1-carboxylate (CAS 1065484-41-4), a certified reference material (molecular formula C18H24N4O3, MW 344.41 g/mol) for analytical method development and quality control.
tert-Butyl 4-(3-methoxyquinoxalin-2-yl)piperazine-1-carboxylate (C18H24N4O3) contains a steroid core, 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.
