Chemical Structure

2-((4-(3-(4-Chlorophenyl)-4,5-dihydro-1H-pyrazol-1-yl)phenyl)sulfonyl)ethanol CAS 3656-22-2 chemical structure

Description

The occurrence of 2-((4-(3-(4-Chlorophenyl)-4,5-dihydro-1H-pyrazol-1-yl)phenyl)sulfonyl)ethanol is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-((4-(3-(4-Chlorophenyl)-4,5-dihydro-1H-pyrazol-1-yl)phenyl)sulfonyl)ethanol (CAS 3656-22-2), molecular formula C19H31NOC6H8O7 and molecular weight 481.59 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C19H31NOC6H8O7, 2-((4-(3-(4-Chlorophenyl)-4,5-dihydro-1H-pyrazol-1-yl)phenyl)sulfonyl)ethanol contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 481.59 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
