6-Chloro-7-methyl-1H-indole-3-sulfonyl chloride CAS 1367937-20-9

Description

Compared with other compounds in its class, the molecular weight of 264.13 g/mol gives 6-Chloro-7-methyl-1H-indole-3-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Chloro-7-methyl-1H-indole-3-sulfonyl chloride (CAS 1367937-20-9) is a high-purity analytical reference standard with the molecular formula C9H7Cl2NO2S and a molecular weight of 264.13 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 6-Chloro-7-methyl-1H-indole-3-sulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
