Chemical Structure
Description
The molecular framework of 2-Chloro-1-[3-(furan-2-yl)-5-(thiophen-2-yl)-4,5-dihydro-1h-pyrazol-1-yl]ethan-1-one (C13H11ClN2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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).
2-Chloro-1-[3-(furan-2-yl)-5-(thiophen-2-yl)-4,5-dihydro-1h-pyrazol-1-yl]ethan-1-one (CAS 796106-54-2) is a high-purity analytical reference standard with the molecular formula C13H11ClN2O2S and a molecular weight of 294.76 g/mol.
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.
