Linuron is an exogenous organic compound with the formula C9H10Cl2N2O2 and an average molecular weight of 249.09 g/mol. At room temperature, it exists as a solid. Linuron belongs to the n-phenylureas, a subclass of benzene and substituted derivatives within the organic compounds. It functions industrially as a biocide and a degradant or impurity.
The compound is released from polyethylene terephthalate plastics and is found in 24 recorded sources. These sources include drinking water and water supply; building and construction materials such as floors and tents or canopies; food processing and cookware including food preservation, processing meats, preparation of malt, and molasses and treatment of molasses; household cleaning and consumer products including bleaching agents, perfumes within detergents and soaps, ash trays, cigar cigarettes, and other smoking requisites; as well as electrical and electronic equipment such as conductors or conductive bodies characterised by the conductive materials, antennas, discharge lamps, and electric switches and hearing aids. Oral exposure is a recorded route for this substance.
Linuron has nine recorded protein targets, which include Cytochrome P450 1A1 (CYP1A1), Cytochrome P450 1A2 (CYP1A2), Cytochrome P450 2B6 (CYP2B6), Cytochrome P450 3A4 (CYP3A4), and five other proteins.
Belongs to the class of organic compounds known as n-phenylureas. N-phenylureas are compounds containing a N-phenylurea moiety, which is structurally characterized by a phenyl group linked to one nitrogen atom of a urea group.
Linuron is a weak competitive inhibitor of androgen receptor binding and it inhibits androgen-induced gene expression in vitro. This may partially contribute to the malformations of androgen-dependent tissues in male rats. (1)
