4-Bromo-5-chloro-2-(4-chlorophenyl)-1H-pyrrole-3-carbonitrile CAS 122453-43-4 chemical structure

Description

The occurrence of 4-Bromo-5-chloro-2-(4-chlorophenyl)-1H-pyrrole-3-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Bromo-5-chloro-2-(4-chlorophenyl)-1H-pyrrole-3-carbonitrile (CAS 122453-43-4) is a high-purity analytical reference standard with the molecular formula C11H5BrCl2N2 and a molecular weight of 315.98 g/mol.

4-Bromo-5-chloro-2-(4-chlorophenyl)-1H-pyrrole-3-carbonitrile (C11H5BrCl2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
