35674-20-5 - Introduction
3,4-Diiodobenzoic acid is a compound with the chemical formula C7H4I2O2. The following is a description of its nature, use, formulation and safety information:
Properties: 3,4-Diiodobenzoic acid is a white to yellow crystalline powder with a special odor. It is almost insoluble in water at normal temperature, but soluble in organic solvents such as alcohol, ether, etc. It has a melting point of about 215-217°C and a thermal decomposition temperature of about 300°C.
Uses: 3,4-Diiodobenzoic acid is often used as an intermediate in organic synthesis in chemical laboratories. It can be used as a raw material or intermediate for the synthesis of other organic compounds, such as drugs, dyes and metal complexes.
preparation method: 3,4-Diiodobenzoic acid can be prepared by diiodination of p-iodobenzoic acid. The general synthesis method is the reaction of iodobenzoic acid with sodium iodate, so that two hydrogen atoms on one of the aromatic rings are replaced by iodine atoms.
Safety information: 3,4-Diiodobenzoic acid is irritating in suspension or solution form and should be handled with care. The dust may cause irritation to the eyes, skin and respiratory system, so wear appropriate protective equipment such as gloves, goggles and protective masks. At the same time, inhalation or ingestion of the compound should be avoided. In case of accidental contact or accident, rinse immediately with plenty of water and seek medical help. In addition, 3,4-Diiodobenzoic acid needs to be kept dry during storage and avoid contact with strong oxidizing and reducing agents to prevent accidental reactions.
