CAS 20638-07-7: 4,4'-(9H-fluorene-9,9-diyl)bis(2-aminophenol)
Description:4,4'-(9H-fluorene-9,9-diyl)bis(2-aminophenol), with the CAS number 20638-07-7, is an organic compound characterized by its unique structure that features a fluorene moiety linked to two 2-aminophenol groups. This compound exhibits properties typical of both aromatic amines and phenolic compounds, which can influence its reactivity and potential applications. It is likely to be a solid at room temperature, with a relatively high melting point due to the presence of multiple aromatic rings that enhance intermolecular interactions. The amino groups in the structure can participate in hydrogen bonding, making the compound potentially useful in various chemical reactions, including those involving nucleophilic substitution or coupling reactions. Additionally, the presence of the fluorene unit may impart interesting electronic properties, making it a candidate for applications in organic electronics or as a dye. However, specific handling precautions should be observed due to the potential toxicity associated with aromatic amines. Overall, this compound's unique structure and functional groups suggest a range of possible applications in materials science and organic synthesis.
