Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 4-{4-[2-(4-bromophenyl)-2-oxoethyl]piperazin-1-yl}-3-nitrobenzoate.
CATO supplies Methyl 4-{4-[2-(4-bromophenyl)-2-oxoethyl]piperazin-1-yl}-3-nitrobenzoate (CAS 478246-67-2), a certified reference material (molecular formula C20H20BrN3O5, MW 462.29 g/mol) for analytical method development and quality control.
Methyl 4-{4-[2-(4-bromophenyl)-2-oxoethyl]piperazin-1-yl}-3-nitrobenzoate (C20H20BrN3O5) 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.
CATO manufactures Methyl 4-{4-[2-(4-bromophenyl)-2-oxoethyl]piperazin-1-yl}-3-nitrobenzoate 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.
