6-[(trifluoromethyl)sulfanyl]-1h-indole-2-carboxylic acid CAS 923800-95-7

Description

Compared with other compounds in its class, the molecular weight of 261.22 g/mol gives 6-[(trifluoromethyl)sulfanyl]-1h-indole-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-[(trifluoromethyl)sulfanyl]-1h-indole-2-carboxylic acid (CAS 923800-95-7), molecular formula C10H6F3NO2S and molecular weight 261.22 g/mol, is a CATO reference standard with documented purity and traceability.

6-[(trifluoromethyl)sulfanyl]-1h-indole-2-carboxylic acid (C10H6F3NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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.

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.
