4-Hydroxybenzenephosphonic acid

Description:
4-Hydroxybenzenephosphonic acid, also known as phenylphosphonic acid, is an organophosphorus compound characterized by the presence of a hydroxyl group and a phosphonic acid functional group attached to a benzene ring. This compound typically appears as a white to off-white crystalline solid and is soluble in water due to the presence of the phosphonic acid group, which can ionize in aqueous solutions. It is known for its applications in various fields, including as a reagent in organic synthesis, a potential chelating agent, and in the development of phosphonic acid derivatives. The presence of the hydroxyl group enhances its reactivity and ability to form hydrogen bonds, which can influence its interactions with other molecules. Additionally, 4-Hydroxybenzenephosphonic acid may exhibit biological activity, making it of interest in medicinal chemistry and materials science. Safety data should be consulted for handling and storage, as with any chemical substance, to ensure proper precautions are taken.
