5-membered Rings

5-membered rings are a group of cyclic organic compounds that contain a five-membered ring with only carbon atoms, also known as cyclopentanes. These compounds are fundamental in organic chemistry due to their stability and presence in many natural products and pharmaceuticals. At CymitQuimica, we offer a variety of high-quality 5-membered ring compounds for your research and industrial needs.
