1H-Pyrrole (Cat No.:R060227) is a five-membered aromatic heterocycle with the molecular formula C₄H₅N, consisting of four carbon atoms and one nitrogen atom. It appears as a colorless to pale yellow liquid with a mildly sweet, chloroform-like odor and is highly sensitive to light and air, readily undergoing polymerization and oxidation. Pyrrole is a fundamental building block in organic chemistry, used in the synthesis of pharmaceuticals, dyes, and conducting polymers such as polypyrrole. Due to its volatility and potential toxicity, it should be handled under inert conditions with appropriate protective equipment.
