5-Bromo-1H-pyrazolo[3,4-b]pyridine-3-sulfonyl chloride CAS 1044941-69-6

Description

The occurrence of 5-Bromo-1H-pyrazolo[3,4-b]pyridine-3-sulfonyl chloride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Bromo-1H-pyrazolo[3,4-b]pyridine-3-sulfonyl chloride (CAS 1044941-69-6) is a high-purity analytical reference standard with the molecular formula C6H3BrClN3O2S and a molecular weight of 296.53 g/mol.

5-Bromo-1H-pyrazolo[3,4-b]pyridine-3-sulfonyl chloride (C6H3BrClN3O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
