Chemical Structure

6-Bromo-2-methyl-2H-indazole-3-sulfonyl chloride CAS 1363380-61-3 chemical structure

Description

Structurally, 6-Bromo-2-methyl-2H-indazole-3-sulfonyl chloride (C8H6BrClN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 309.57 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

6-Bromo-2-methyl-2H-indazole-3-sulfonyl chloride (CAS 1363380-61-3) is a high-purity analytical reference standard with the molecular formula C8H6BrClN2O2S and a molecular weight of 309.57 g/mol.

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.
