Chemical Structure

2-(3-Chlorophenyl)-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazole-3-carboxylic acid CAS 2416673-66-8 chemical structure

Description

The molecular framework of 2-(3-Chlorophenyl)-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazole-3-carboxylic acid (C13H11ClN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
