CAS 10544-50-0: Cyclic octaatomic sulfur

Description: Cyclic octaatomic sulfur, also known as S8, is a molecular form of sulfur characterized by its crown-shaped cyclic structure consisting of eight sulfur atoms. This allotrope is the most stable and common form of elemental sulfur at room temperature. It typically appears as a yellow, crystalline solid and is insoluble in water but soluble in organic solvents such as carbon disulfide and benzene. The S8 molecule exhibits a crown-like conformation, which contributes to its stability and unique properties. It has a relatively low melting point and sublimates easily, transitioning from solid to gas without passing through a liquid phase. Cyclic octaatomic sulfur is known for its role in various chemical reactions, including the formation of polysulfides and its use in vulcanization processes in rubber manufacturing. Additionally, it is an important component in the production of sulfuric acid and other sulfur compounds. Its CAS number, 10544-50-0, is used for identification in chemical databases and regulatory frameworks.
