O-BENZENEDIACETIC ACID - Introduction
1,2-Phenylenediacetic acid(1,2-Phenylenediacetic acid) is an organic compound with the chemical formula C10H10O4. It is a white crystal or crystalline powder, soluble in organic solvents such as ethanol, acetone and dichloromethane, and insoluble in water.
One of the main uses of 1,2-Phenylenediacetic acid is as an organic synthesis intermediate for the synthesis of other organic compounds. It can be used in the preparation of fluorescent dyes, organic catalysts, optical materials and pharmaceuticals. In addition, it can also be used as a component of metal surface treatment agents and corrosion inhibitors.
The preparation of 1,2-Phenylenediacetic acid is usually achieved by the ester polycondensation reaction of dicarboxylic acids. A common method is the reaction of 1,2-Phenylenediacetic acid dimethyl ester with sodium hydroxide followed by acidification to give the target product.
Regarding safety information, 1,2-Phenylenediacetic acid is relatively safe under normal conditions of use. However, it may be irritating to the eyes, skin and respiratory tract, so it is necessary to pay attention to protective measures when using it, such as wearing protective glasses, gloves and protective masks. Avoid inhaling its dust or solution, avoid contact with skin and eyes. If contact occurs, immediately flush the affected area with clean water and seek medical help. At the same time, 1,2-Phenylenediacetic acid should be stored in a sealed, dry place, away from fire and oxidizing agents.
