1,4-dichlorobenzene dihydrodiol, also known as 3,6-dichloro-cis-1,2-dihydroxycyclohexa-3,5-diene, is a member of the class of compounds known as chlorohydrins. Chlorohydrins are alcohols substituted by a chlorine atom at a saturated carbon atom otherwise bearing only hydrogen or hydrocarbyl groups. 1,4-dichlorobenzene dihydrodiol is soluble (in water) and a very weakly acidic compound (based on its pKa). 1,4-dichlorobenzene dihydrodiol can be found in a number of food items such as parsley, white lupine, radish, and mamey sapote, which makes 1,4-dichlorobenzene dihydrodiol a potential biomarker for the consumption of these food products.
