5-Bromo-4-chloro-1H-indol-3-yl sulfate potassium salt 6578-07-0 X-Sulfate . potassium salt;Sulfuric acid-mono-(5-bromo-4-chloro-1H-indol-3-yl) ester . potassium salt (CAS 6578-07-0) is a high-purity analytical reference standard with the molecular formula C8H12BrClNO4SK and a molecular weight of 372.70 g/mol.
Based on its molecular formula C8H12BrClNO4SK, 5-Bromo-4-chloro-1H-indol-3-yl sulfate potassium salt 6578-07-0 X-Sulfate . potassium salt;Sulfuric acid-mono-(5-bromo-4-chloro-1H-indol-3-yl) ester . potassium salt contains a salt form, an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 372.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
