Chemical Structure
Description
CATO supplies Tert-butyl 4-(5-bromo-3-nitropyridin-2-yl)piperazine-1-carboxylate (CAS 1221792-73-9), a certified reference material (molecular formula C14H19BrN4O4, MW 387.23 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Tert-butyl 4-(5-bromo-3-nitropyridin-2-yl)piperazine-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 387.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), Tert-butyl 4-(5-bromo-3-nitropyridin-2-yl)piperazine-1-carboxylate 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.
