Description
(1-(tert-butoxycarbonyl)-5-((4-(tert-butoxycarbonyl)piperazin-1-yl)methyl)-1H-indol-2-yl)boronic acid (CAS 771477-41-9), molecular formula C23H34BN3O6 and molecular weight 459.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1-(tert-butoxycarbonyl)-5-((4-(tert-butoxycarbonyl)piperazin-1-yl)methyl)-1H-indol-2-yl)boronic acid (C23H34BN3O6) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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. 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), (1-(tert-butoxycarbonyl)-5-((4-(tert-butoxycarbonyl)piperazin-1-yl)methyl)-1H-indol-2-yl)boronic acid 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.
