2. Analytical Chemistry: it can be used as a chemical reagent, commonly used in fluorescence analysis, spectral analysis and catalytic analysis and other fields.

Method:
disodium is generally prepared by the following steps:
1. Mix 4-nitrophenol and sulfuric acid.
2. The mixture is reacted at an appropriate temperature to generate 4-nitrocatechol sulfate.
3. Finally, 4-nitrocatechol sulfate is reacted with potassium salt to produce disodium.

Safety Information:
1. disodium is harmful to the human body and may cause irritation to the respiratory tract, skin and eyes. Wear appropriate personal protective equipment when using.
2. In the operation should comply with the safe operation procedures, avoid inhalation, contact with skin and eyes.
3. Storage should be placed in a cool, dry, well-ventilated place, with other substances stored in isolation, avoid contact with oxidants and flammable materials, to prevent the occurrence of fire and explosion.
4. If you take it by mistake or enter the eye by mistake, you should seek medical attention immediately and inform the doctor of the name and chemical formula of the chemical used.
