MACROCYCLES/CROWN ETHERS

Products protected by valid patents are not offered for sale in countries where the sale of such products constitutes a patent infringement and its liability is at buyer's risk.

Crown ethers are organic compounds that have a special ring-shaped structure consisting of a chain of oxygen atoms linked by carbon atoms. They are used in chemical research and analysis due to their ability to selectively bind certain metal ions. Crown ethers can "coat" and isolate metal ions such as sodium, potassium or calcium in aqueous solutions, which makes them relevant for various applications in chemistry, biology and medicine. Their ability to selectively bind metal ions has contributed to crown ethers being investigated in various fields such as catalysis, chemical separation and drug development.
