1-(4-CHLOROPHENYL)-1H-PYRROLE

Model: 5044-38-2
1-(4-Chlorophenyl)-1H-pyrrole is an N-aryl pyrrole in which a π-excessive pyrrole ring is linked directly to a 4-chlorophenyl group via the pyrrole nitrogen, creating a conformationally constrained, conjugated scaffold; the electron-withdrawing para-chloro substituent enhances the compound’s stability and lipophilicity while providing a versatile halogen handle for further functionalization through cross-coupling reactions in medicinal chemistry and materials science.

1-(4-Chlorophenyl)-1H-pyrrole (CAS 5044-38-2) is a heterocyclic aromatic compound belonging to the pyrrole family — a five-membered ring structure containing one nitrogen atom — with a 4-chlorophenyl substituent directly attached to the pyrrole nitrogen. The molecular formula is C₁₀H₈ClN, with a molecular weight of 177.63 g/mol, and the compound is supplied at purities ranging from 95% to 98%.

In medicinal chemistry, 1-(4-chlorophenyl)-1H-pyrrole is a highly versatile building block. As a fragment molecule, 1-(4-chlorophenyl)-1H-pyrrole provides a structural foundation for molecular linking, expansion, and modification in drug discovery programs, serving as a key intermediate for the synthesis of biologically active molecules, including antimicrobial, anticancer, and anti-inflammatory agents. Studies have demonstrated that 1-(4-chlorophenyl)-1H-pyrrole exhibits significant antiproliferative effects against various cancer cell lines, including liver cancer (HepG-2, IC₅₀ = 5.0 μM) and breast cancer (MCF-7, IC₅₀ = 3.0 μM). Its derivatives have also shown antimicrobial activity and have been explored for their anti-inflammatory properties.

In materials science, 1-(4-chlorophenyl)-1H-pyrrole has been investigated for use in organic electronics, including organic light-emitting diodes (OLEDs) and solar cells, leveraging its conjugated π-system for charge transport properties. The 4-chlorophenyl moiety can be further functionalized, allowing the introduction of additional substituents or modifications to tailor the compound’s properties for specific applications.

1-(4-Chlorophenyl)-1H-pyrrole is also a valuable research chemical in chemical synthesis, and it is listed in the National Cancer Institute (NCI) database under NSC 116796.

Frequently Asked Questions (FAQ)

Q1:What is the significance of the LogP value?

A: The calculated LogP of 3.13 indicates moderate to high lipophilicity, suggesting good membrane permeability and potential oral bioavailability for drug-like applications. Compared to unsubstituted 1-phenylpyrrole (LogP = 2.53), the chlorine substitution increases the compound’s lipophilicity, which may enhance its ability to cross cell membranes and reach biological targets.


Q2: Has 1-(4-Chlorophenyl)-1H-pyrrole demonstrated anticancer activity?

A: Yes. Studies have shown that this compound exhibits significant antiproliferative effects against various cancer cell lines, including liver cancer (HepG-2, IC₅₀ = 5.0 μM) and breast cancer (MCF-7, IC₅₀ = 3.0 μM). These findings suggest its potential as a lead scaffold for anticancer drug development.
