6,6',7,7'-TETRAHYDROXY-4,4,4',4'-TETRAMETHYL-2,2'-SPIROBICHROMAN is a novel compound with good biocompatibility and biodegradability, which is being developed for use as radiation-absorbent materials, drug delivery systems, polymerisation catalysts and for biocompatible and biodegradable substances applications. In addition, it has antioxidant, polymer stabiliser and surfactant capabilities. A key aspect of its function as an antioxidant lies in its ability to scavenge reactive oxygen species and reactive nitrogen, thus contributing to its multifaceted properties.
