Chemical Structure
Description
3-Bromo-5,6,7-trifluoro-1H-indole (C8H3BrF3N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3-Bromo-5,6,7-trifluoro-1H-indole (CAS 2759141-82-5) is a high-purity analytical reference standard with the molecular formula C8H3BrF3N and a molecular weight of 250.02 g/mol.
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.
