General description

1,2-Dihydroxybenzene (a phenolic compound) is a useful industrial chemical. It is an ortho isomeric form of dihydroxybenzene. It is commonly referred to as catechol or pyrocatechol. Its standard molar enthalpy of combustion and sublimation at 298.15K have been evaluated by static-bomb calorimetry and microcalorimetry, respectively.

Application

1,2-Dihydroxybenzene may be used as raw material for the industrial synthesis of rubber, dyes, plastics, pharmaceuticals and cosmetics.
1,2-Dihydroxybenzene in combination with amberlite XAD-2, can be used as a chelating resin in the determination of metal ions, using atomic absorption spectrophotometry (AAS).
