5-membered Heterocycles
5-membered heterocycles are organic compounds formed by a five-membered ring containing one or more heteroatoms such as nitrogen, oxygen, or sulfur. These compounds often result from the fusion of a benzene ring and a 5-membered heterocycle, creating diverse structures with unique chemical properties. 5-membered heterocycles are widely used in pharmaceuticals, agrochemicals, and materials science due to their reactivity and versatility. At CymitQuimica, we offer a comprehensive selection of high-quality 5-membered heterocycles to support your research and industrial applications.
