3-Chloro-2-phenyl-1-(phenylsulfonyl)-1H-indole CAS 88207-48-1

Description

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.

3-Chloro-2-phenyl-1-(phenylsulfonyl)-1H-indole (CAS 88207-48-1), molecular formula C20H14ClNO2S and molecular weight 367.85 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C20H14ClNO2S, 3-Chloro-2-phenyl-1-(phenylsulfonyl)-1H-indole contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 367.85 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
