Chemical Structure
Description
The molecular framework of 2-(2,4-Dichlorophenyl)-3a,4,5,6-tetrahydrocyclopenta[c]pyrazol-3(2H)-one (C12H10Cl2N2O) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
2-(2,4-Dichlorophenyl)-3a,4,5,6-tetrahydrocyclopenta[c]pyrazol-3(2H)-one (CAS 1304083-48-4), molecular formula C12H10Cl2N2O and molecular weight 269.13 g/mol, is a CATO reference standard with documented purity and traceability.
