Description
Compared with other compounds in its class, the molecular weight of 418.31 g/mol gives 5-Bromo-N,N-dimethyl-1H,1'H-[3,4'-biindole]-1-sulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-N,N-dimethyl-1H,1'H-[3,4'-biindole]-1-sulfonamide (CAS 89346-37-2) is a high-purity analytical reference standard with the molecular formula C18H16BrN3O2S and a molecular weight of 418.31 g/mol.
The molecular framework of 5-Bromo-N,N-dimethyl-1H,1'H-[3,4'-biindole]-1-sulfonamide (C18H16BrN3O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine 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.
