Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 356.39 g/mol gives 5-Bromo-6-chloro-3-iodo-1H-indole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Bromo-6-chloro-3-iodo-1H-indole (CAS 2306263-63-6), a certified reference material (molecular formula C8H4BrClIN, MW 356.39 g/mol) for analytical method development and quality control.
The molecular framework of 5-Bromo-6-chloro-3-iodo-1H-indole (C8H4BrClIN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
