Chemical Structure
Description
The occurrence of tert-Butyl 4-(5-bromo-2-chlorobenzyl)piperazine-1-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
tert-Butyl 4-(5-bromo-2-chlorobenzyl)piperazine-1-carboxylate (CAS 1704074-43-0), molecular formula C16H22BrClN2O2 and molecular weight 389.72 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl 4-(5-bromo-2-chlorobenzyl)piperazine-1-carboxylate (C16H22BrClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures tert-Butyl 4-(5-bromo-2-chlorobenzyl)piperazine-1-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
