Chemical Structure
Description
The molecular framework of 3-Bromo-5-fluoro-1-(p-toluenesulfonyl)indole (C15H11BrFNO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
3-Bromo-5-fluoro-1-(p-toluenesulfonyl)indole (CAS 887338-48-9) is a high-purity analytical reference standard with the molecular formula C15H11BrFNO2S and a molecular weight of 368.22 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Bromo-5-fluoro-1-(p-toluenesulfonyl)indole 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.
