Chemical Structure
Description
The molecular framework of 3-(4-Ethylphenyl)-4-iodo-1H-pyrazole (C11H11IN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine 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.
3-(4-Ethylphenyl)-4-iodo-1H-pyrazole (CAS 1343634-88-7), molecular formula C11H11IN2 and molecular weight 298.12 g/mol, is a CATO reference standard with documented purity and traceability.
