Chemical Information
Namecatechol
Description1,2-dihydroxybenzene, also known as pyrocatechol or 2-hydroxyphenol, is a member of the class of compounds known as catechols. Catechols are compounds containing a 1,2-benzenediol moiety. 1,2-dihydroxybenzene is soluble (in water) and a very weakly acidic compound (based on its pKa). 1,2-dihydroxybenzene can be found in a number of food items such as orange bell pepper, squashberry, cauliflower, and allspice, which makes 1,2-dihydroxybenzene a potential biomarker for the consumption of these food products. 1,2-dihydroxybenzene can be found primarily in blood, feces, saliva, and urine, as well as throughout most human tissues. 1,2-dihydroxybenzene exists in all living organisms, ranging from bacteria to humans. In humans, 1,2-dihydroxybenzene is involved in a couple of metabolic pathways, which include disulfiram action pathway and tyrosine metabolism. 1,2-dihydroxybenzene is also involved in several metabolic disorders, some of which include hawkinsinuria, tyrosinemia type I, dopamine beta-hydroxylase deficiency, and monoamine oxidase-a deficiency (MAO-A). Moreover, 1,2-dihydroxybenzene is found to be associated with schizophrenia. 1,2-dihydroxybenzene is formally rated as possibly a carcinogenic (IARC 2B) potentially toxic compound.
