In the wonderful world of chemistry, the discovery of new substances is often accompanied by surprises and surprises, and the discovery of 18-crown-6 CAS 17455-13-9 is no exception. In 1967, when chemist Charles J. Pedersen was conducting a routine organic synthesis experiment, he originally studied a linear polyether compound, but accidentally obtained a compound with a ring structure, and after further research, 18-crown-6 came into people’s vision. At the time, the chemical community was very new to this compound with a special ring structure and multiple oxygen atoms. Pedersen dug deeper and found that 18-crown-6 had many unusual properties, such as its ability to form stable complexes with metal ions, which was a new discovery in chemistry at the time. It made scientists realize that in addition to traditional chemical bond interactions, there are special interactions with ions through large ring structures, which opened the door to crown ether chemistry and laid the foundation for the development of subsequent supramolecular chemistry.
18-crown-6, the name indicates the uniqueness of its structure. “18” represents the total number of atoms in the ring, and “6” represents the number of oxygen atoms in it. It consists of 12 carbon atoms and six oxygen atoms holding hands in a ring structure, like a delicate molecular bracelet, this special structure is very rare in the field of chemistry. In this ring, oxygen atoms, by virtue of their electronegativity, make the entire molecule with a certain polarity, while carbon atoms form the basic skeleton of the molecule, holding up the entire structure. It is this ring structure of carbon and oxygen atoms that gives 18-crown-6 CAS 17455-13-9 its unique properties, enabling it to form stable complexes with metal ions. It usually occurs as a white crystal at room temperature. Its melting point is between 42 and 45°C, which is not so hot that a little heating can transform it from a solid to a liquid. The boiling point is 116 ° C, and under certain pressure conditions, it gradually turns into a gas. It is also soluble in water and can interact with water molecules to form a uniform mixing system.
With its unique molecular structure, 18-crown-6 CAS 17455-13-9 has shown excellent application value in many fields, and has become one of the key materials to promote technological progress in various fields, providing innovative solutions to solve practical problems.
