NSC 266055 - Introduction
(2,5-dioxo-2) acetic, also known as (2,5-dioxo-2, O-2) acetic acid, is an organic compound. its structure contains a maleyl group and an acetic acid group.
(2,5-Dioxo-2,) acetic acid is a solid, common form is white crystal. It is slightly soluble in water, but can be dissolved in organic solvents. It has strong acidity.
(2,5-dioxo-2,) acetic acid is widely used in chemical and pharmaceutical fields. It can be used as an important intermediate in organic synthesis for the synthesis of other compounds. In addition, it can also be used as a chelating agent, stabilizer and catalyst component.
(2,5-dioxo-2,) The preparation method of acetic acid can be completed by the reaction of maleoyl chloride and acetic acid. Maleoyl chloride is first dissolved in an organic solvent and reacted with acetic acid at low temperature to produce (2,5-dioxo-2, fine) acetic acid.
When using (2,5-Dioxo-2,) acetic acid, care should be taken to avoid contact with skin and eyes to prevent irritation. During use and storage, good ventilation should be ensured. At the same time, it should be stored in a dry, cool place, away from fire and oxidizing agents.
