Pyrrolidine(CAT: R052315) is a saturated five-membered heterocycle containing four carbon atoms and one nitrogen atom, with the molecular formula C₄H₉N. This secondary amine is a colorless, highly hygroscopic liquid with a characteristic amine-like odor. It serves as an important building block in organic synthesis, particularly in the preparation of pharmaceuticals, agrochemicals, and fine chemicals. Pyrrolidine is commonly used as a precursor for alkaloid synthesis, a catalyst or base in various reactions, and a structural motif in bioactive molecules. Its cyclic structure imparts distinct conformational and electronic properties, making it valuable in medicinal chemistry, material science, and asymmetric synthesis research.
