Chemical Structure
Description
The molecular framework of 5-Bromo-1'H,3H-[2,3'-biindol]-3-one (C16H9BrN2O) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
CATO supplies 5-Bromo-1'H,3H-[2,3'-biindol]-3-one (CAS 92967-81-2), a certified reference material (molecular formula C16H9BrN2O, MW 325.16 g/mol) for analytical method development and quality control.
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.
