Description

Compared with other compounds in its class, the molecular weight of 257.71 g/mol gives 6-chloro-7-fluoro-1H-indole-3-sulfonic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-chloro-7-fluoro-1H-indole-3-sulfonic acid (CAS 2231234-37-8) is a high-purity analytical reference standard with the molecular formula C8H13ClFNO3S and a molecular weight of 257.71 g/mol.

6-chloro-7-fluoro-1H-indole-3-sulfonic acid (C8H13ClFNO3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
