Abstract:
In 2022, the European Chemicals Agency (ECHA) made a statement concluding that iodine is an endocrine disruptor (ED). "We stress the fact that the ECHA opinion ECHA/BPC/357/2022 is based on their misguidedly zooming in on exclusively the biocidal products (e.g., hand disinfectants, disinfection of animals' teats/udder, embalming fluids before cremation, etc.) that contain molecular iodine (I2), entirely neglecting [see the 2013 ECHA Regulation (EU) n°528/2012 describing iodine as being of "great importance for human health". Clearly, the current sweeping and erroneous classification of "iodine" as an endocrine disruptor is ill-advised. We moreover call upon the scientific and medical community at large to use the accurate scientific nomenclature, i.e., iodide or iodate instead of "iodine" when referring to iodized salts and food prepared there with. Drugs, diagnostic agents, and synthetic chemicals containing the element iodine in the form of covalent bonds must be correctly labelled ''iodinated'', if possible, using each time their distinctive and accurate chemical or pharmacological name.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
