CAS 22987-21-9: 2-Hydroxyethanephosphonic acid

Description:2-Hydroxyethanephosphonic acid, also known as HEPA, is an organophosphorus compound characterized by the presence of a phosphonic acid group and a hydroxyl group attached to an ethane backbone. This compound is typically a colorless to pale yellow liquid or solid, depending on its form and purity. It is soluble in water and exhibits moderate stability under standard conditions. HEPA is known for its role as a chelating agent and is utilized in various applications, including agriculture as a plant growth regulator and in the synthesis of other phosphorus-containing compounds. The presence of the hydroxyl group enhances its reactivity, allowing it to participate in various chemical reactions, including esterification and phosphorylation. Additionally, 2-Hydroxyethanephosphonic acid can interact with metal ions, making it useful in formulations aimed at improving nutrient uptake in plants. Safety data indicates that, while it should be handled with care due to potential irritant properties, it is not classified as highly toxic.
