Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 397.23 g/mol gives 3-Iodo-1-tosyl-1H-indole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Iodo-1-tosyl-1H-indole (CAS 170456-80-1) is a high-purity analytical reference standard with the molecular formula C15H12INO2S and a molecular weight of 397.23 g/mol.
3-Iodo-1-tosyl-1H-indole (C15H12INO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
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.
