Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyl 4-(4-bromo-2-nitrophenyl)-piperazine-1-carboxylate.
CATO supplies tert-Butyl 4-(4-bromo-2-nitrophenyl)-piperazine-1-carboxylate (CAS 474329-57-2), a certified reference material (molecular formula C15H20BrN3O4, MW 386.24 g/mol) for analytical method development and quality control.
tert-Butyl 4-(4-bromo-2-nitrophenyl)-piperazine-1-carboxylate (C15H20BrN3O4) contains a flavonoid core, an amide 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.
