A benzenediol comprising of a benzene core carrying two hydroxy substituents ortho to each other.

1,2-Dihydroxybenzene (catechol) can induce spontaneous convulsive activity   in the anaesthetized mouse.[1]
1,2-Dihydroxybenzene can produce myoclonic jerks in the rat.[2]
1,2-Dihydroxybenzene-containing compounds bind to and cap cysteine residues of tau and prevent its aggregation by hindering interactions between tau molecules, further, we show that orally administered DL-isoproterenol, an adrenergic receptor agonist whose skeleton includes 1,2-dihydroxybenzene and which penetrates the brain, reduces the levels of detergent-insoluble tau, neuronal loss and reverses neurofibrillary tangle-associated brain dysfunction; thus, compounds that target the cysteine residues of tau may prove useful in halting the progression of Alzheimer’s disease and other tauopathies.[3]
