4-Bromo-1-tosyl-1H-pyrrolo[2,3-b]pyridine CAS 348640-07-3

Description

Compared with other compounds in its class, the molecular weight of 351.22 g/mol gives 4-Bromo-1-tosyl-1H-pyrrolo[2,3-b]pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Bromo-1-tosyl-1H-pyrrolo[2,3-b]pyridine (CAS 348640-07-3), a certified reference material (molecular formula C14H11BrN2O2S, MW 351.22 g/mol) for analytical method development and quality control.

4-Bromo-1-tosyl-1H-pyrrolo[2,3-b]pyridine (C14H11BrN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, 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.

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.

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.
