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 Di-tert-butyl (4-bromo-3-chloro-2-nitrophenyl)iminodicarbonate.
CATO supplies Di-tert-butyl (4-bromo-3-chloro-2-nitrophenyl)iminodicarbonate (CAS 2611563-28-9), a certified reference material (molecular formula C16H20BrClN2O6, MW 451.70 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, Di-tert-butyl (4-bromo-3-chloro-2-nitrophenyl)iminodicarbonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 451.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Di-tert-butyl (4-bromo-3-chloro-2-nitrophenyl)iminodicarbonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
