Description

Clofentezine is an exogenous organic compound with the formula C14H8Cl2N4 and an average molecular weight of 303.15 g/mol. At room temperature, it exists as a solid. Clofentezine belongs to the halobenzenes, a subclass of benzene and substituted derivatives within the organic compounds. Functioning as a tetrazine acaricide, this compound is used as a mite growth regulator. It has been recorded in five sources, including pesticides in agriculture and land management, drinking water and water supply, and food, food processing and cookware, specifically in the preparation of malt, the preparation of wine or sparkling wine, and molasses and the treatment of molasses. Exposure routes include oral, inhalation, and touch. In biological systems, clofentezine interacts with 15 recorded protein targets. These include the bile salt export pump (ABCB11), C-C motif chemokine 2 (CCL2), collagen alpha-1(III) chain (COL3A1), cytochrome P450 1A2 (CYP1A2), and 11 other proteins.

Health Effects

No adverse health effects attributable to clofentezine were detecte during medical surveillance between 1985 and 2004 in workers at a plant manufacturing clofentezine. The medical examination included an extensive physical examination (including height, body weight, skin, ear, nose and throat, and respiratory, nervous, alimentary, reticulo-endothelial and cardiovascular systems, and locomotion) and specific tests for blood pressure and vision. The examination also included tests for hearing, lung function, urine analysis and blood tests when these were considered appropriate. (Makhteshim Agan Industries Ltd, 2004). However, there is an increase of incidences of thyroid adenomas, adenocarcinomas, thyroid hyperplasia, agglomeration of colloid and thyroid hormones in rats receiving prolonged treatment of high dose of clofentezine.
