CAS 143-74-8: Phenol, 4,4'-(1,1-dioxido-3H-2,1-benzoxathiol-3-ylidene)bis-

Description: Phenol, 4,4'-(1,1-dioxido-3H-2,1-benzoxathiol-3-ylidene)bis-, also known by its CAS number 143-74-8, is a chemical compound characterized by its phenolic structure combined with a benzoxathiol moiety. This compound typically exhibits properties associated with both phenols and heterocyclic compounds, including potential antioxidant and antimicrobial activities. The presence of the dioxido group suggests that it may have enhanced reactivity or stability under certain conditions. It is generally soluble in organic solvents and may have limited solubility in water, which is common for many phenolic compounds. The compound's structure allows for various applications in organic synthesis, materials science, and potentially in pharmaceuticals, given the biological activity often associated with phenolic derivatives. Safety data should be consulted for handling and exposure risks, as phenolic compounds can be toxic and irritative. Overall, this compound represents a unique intersection of organic chemistry and potential applications in various fields.
