2,7-dihydroxynaphthalene is an organic compound. The following is an introduction to its properties, uses, manufacturing methods, and safety information:

nature:

-It is insoluble in water, but can dissolve in organic solvents such as alcohols and ethers.

-It is an aromatic compound with a strong phenolic odor.

Purpose:

-2,7-dihydroxynaphthalene is also used as an important reagent for research and laboratory analysis.

Manufacturing method:
