6-membered Heterocycles

6-membered heterocycles are organic compounds that feature a six-membered ring containing one or more heteroatoms such as nitrogen, oxygen, or sulfur. These structures are prevalent in numerous bioactive molecules and pharmaceuticals due to their stability and reactivity. 6-membered heterocycles are also essential in the synthesis of agrochemicals, dyes, and advanced materials. At CymitQuimica, we offer a diverse selection of high-quality 6-membered heterocycles to support your research and industrial applications.
