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-(3-(4-bromo-2-fluorophenoxy)propyl)piperazine-1-carboxylate.
tert-Butyl 4-(3-(4-bromo-2-fluorophenoxy)propyl)piperazine-1-carboxylate (CAS 1704065-39-3), molecular formula C18H26BrFN2O3 and molecular weight 417.31 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl 4-(3-(4-bromo-2-fluorophenoxy)propyl)piperazine-1-carboxylate (C18H26BrFN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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.
CATO manufactures tert-Butyl 4-(3-(4-bromo-2-fluorophenoxy)propyl)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.
