Chemical Structure

6-Chloro-1-(phenylsulfonyl)-1H-indole CAS 231295-53-7 chemical structure

Description

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.

6-Chloro-1-(phenylsulfonyl)-1H-indole (CAS 231295-53-7) is a high-purity analytical reference standard with the molecular formula C14H10ClNO2S and a molecular weight of 291.75 g/mol.

6-Chloro-1-(phenylsulfonyl)-1H-indole (C14H10ClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
