1-(4-Chlorophenyl)-2-phenyl-1,5,6,7-tetrahydro-4H-indol-4-one CAS 338979-36-5

Description

The occurrence of 1-(4-Chlorophenyl)-2-phenyl-1,5,6,7-tetrahydro-4H-indol-4-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(4-Chlorophenyl)-2-phenyl-1,5,6,7-tetrahydro-4H-indol-4-one (CAS 338979-36-5), molecular formula C20H16ClNO and molecular weight 321.80 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C20H16ClNO, 1-(4-Chlorophenyl)-2-phenyl-1,5,6,7-tetrahydro-4H-indol-4-one contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 321.80 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
