Chemical Structure
Description
As a certified reference material (CRM), tert-Butyl 4-(2-bromo-5-methoxybenzyl)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.
tert-Butyl 4-(2-bromo-5-methoxybenzyl)piperazine-1-carboxylate (CAS 339152-01-1) is a high-purity analytical reference standard with the molecular formula C17H25BrN2O3 and a molecular weight of 385.30 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, tert-Butyl 4-(2-bromo-5-methoxybenzyl)piperazine-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 385.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
