  <description>Bithionol is an organic compound with the chemical formula C12H6Cl4O2S and an average molecular weight of 356.05 g/mol. Bithionol belongs to the aryl thioethers, a subclass of thioethers within the organic compounds.

This compound is associated with 11 recorded sources across several sectors. Within healthcare, pharmaceuticals, and veterinary products, it is found in antibiotics. In the realm of household cleaning and consumer products, it is present in soap detergents, bleaching agents, and perfumes within detergents and soaps. Its use in food, food processing, and cookware includes food preservation, processing meats, and fermentation processes for beer. Additionally, it is released from electrical and electronic equipment, specifically electrodes, radio transmission systems, amplifiers, and conductors or conductive bodies characterised by the conductive materials. Recorded exposure routes for this substance include oral and inhalation.

At the molecular level, bithionol acts on four recorded protein targets. It functions as an inhibitor of the estrogen receptor (ESR1), the estrogen receptor beta (ESR2), the calpain-2 catalytic subunit (CAPN2), and the induced myeloid leukemia cell differentiation protein Mcl-1 (MCL1).</description>
