Description
(S)-4-(2-Bromo-6-nitrophenyl)-1-(tert-butoxy-carbonyl)piperazine-2-carboxylic acid 1786899-70-4 (CAS 1786899-70-4) is a high-purity analytical reference standard with the molecular formula C16H20BrN3O6 and a molecular weight of 430.25 g/mol.
The molecular framework of (S)-4-(2-Bromo-6-nitrophenyl)-1-(tert-butoxy-carbonyl)piperazine-2-carboxylic acid 1786899-70-4 (C16H20BrN3O6) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), (S)-4-(2-Bromo-6-nitrophenyl)-1-(tert-butoxy-carbonyl)piperazine-2-carboxylic acid 1786899-70-4 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.
