Chemical Structure

6-cyclopropyl-1H-indole-3-sulfonyl chloride CAS 2231234-20-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 263.78 g/mol gives 6-cyclopropyl-1H-indole-3-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-cyclopropyl-1H-indole-3-sulfonyl chloride (CAS 2231234-20-9) is a high-purity analytical reference standard with the molecular formula C11H18ClNO2S and a molecular weight of 263.78 g/mol.

6-cyclopropyl-1H-indole-3-sulfonyl chloride (C11H18ClNO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
