Crown Ether
Crown ethers are a type of macrocycle known for their ability to form stable complexes with various cations due to the arrangement of oxygen atoms within their ring structure. These compounds are used in phase-transfer catalysis, molecular recognition, and as ion transport agents. Their unique structure enables selective binding to specific metal ions, making them valuable tools in both chemical and biochemical applications. At CymitQuimica, we provide a wide range of crown ethers to support your research and industrial needs.
