Chemical Structure
Description
CATO supplies Tert-butyl 4-(2-bromo-3-isopropyl-1H-indol-5-yl)piperidine-1-carboxylate (CAS 2171029-26-6), a certified reference material (molecular formula C21H29BrN2O2, MW 421.37 g/mol) for analytical method development and quality control.
The molecular framework of Tert-butyl 4-(2-bromo-3-isopropyl-1H-indol-5-yl)piperidine-1-carboxylate (C21H29BrN2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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), Tert-butyl 4-(2-bromo-3-isopropyl-1H-indol-5-yl)piperidine-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.
