Chemical Structure
Description
As a certified reference material (CRM), S-(3-(5-Bromo-1H-indol-3-yl)-2-oxopropyl) ethanethioate 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.
CATO supplies S-(3-(5-Bromo-1H-indol-3-yl)-2-oxopropyl) ethanethioate (CAS 919295-76-4), a certified reference material (molecular formula C13H12BrNO2S, MW 326.21 g/mol) for analytical method development and quality control.
The molecular framework of S-(3-(5-Bromo-1H-indol-3-yl)-2-oxopropyl) ethanethioate (C13H12BrNO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
