iodiert

Iodiert is an adjective used in chemistry and related fields to describe substances that contain iodine or have been produced by introducing iodine into a molecule. The process of introducing iodine is called iodination or iodation, and it is typically achieved through electrophilic iodination using molecular iodine (I2) with an oxidant, or by using reagents such as N-iodosuccinimide. Iodination can target aromatic rings, alkenes, or other reactive sites, and the chosen method depends on the desired position and selectivity.

In biochemistry and physiology, iodination has specific roles. For example, iodine is incorporated into the amino acid tyrosine during the synthesis of thyroid hormones, forming compounds such as monoiodotyrosine and diiodotyrosine, which couple to produce thyroxine (T4) and triiodothyronine (T3). In nutrition, iodination of table salt—producing iodized salt with potassium iodide or potassium iodate—serves as a public health measure to prevent iodine deficiency disorders.

In medicine and research, iodinated compounds are widely used: iodinated contrast agents enhance X-ray and CT imaging, and radioactive iodine isotopes (such as iodine-125 or iodine-131) are employed in diagnostics and radiotherapy, as well as in radiolabeling experiments to study biological processes.

Safety and regulation are important considerations, since iodine compounds can be irritants or toxic in excess, and iodinated reagents require proper handling and disposal.
