Chemical Structure
Description
As a certified reference material (CRM), 4-(4-Bromo-2-nitrophenoxy)piperidine hydrochloride 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.
4-(4-Bromo-2-nitrophenoxy)piperidine hydrochloride (CAS 1220020-95-0), molecular formula C11H13BrN2O3HCl and molecular weight 337.60 g/mol, is a CATO reference standard with documented purity and traceability.
4-(4-Bromo-2-nitrophenoxy)piperidine hydrochloride (C11H13BrN2O3HCl) 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, 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.
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.
