Description
Compared with other compounds in its class, the molecular weight of 368.84 g/mol gives 3-Chloro-1-(phenylsulfonyl)-2-(pyridin-2-yl)-1H-indole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Chloro-1-(phenylsulfonyl)-2-(pyridin-2-yl)-1H-indole (CAS 88207-54-9), molecular formula C19H13ClN2O2S and molecular weight 368.84 g/mol, is a CATO reference standard with documented purity and traceability.
3-Chloro-1-(phenylsulfonyl)-2-(pyridin-2-yl)-1H-indole (C19H13ClN2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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).
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.
