Iodine as a product is usually solid, with a purplish-black metallic luster, and is heavy material like metals. It is liquefied even at a comparatively low temperature and can quickly vaporize by sublimating solid iodine like dry ice. It has a distinctive smell. It is rare for material to easily take the form of vapor, liquid, and solid. It is widely used in producing various kinds of Iodine compounds and is used in many areas due to its strong reactivity.
Iodine is used in various applications such as X-Ray contrast media, pharmaceuticals, LCD polarizing films, Animal feed, Iodophors, Fluorochemicals, Biocides, Nylon, Human Nutrition, Povidone-Iodine, and more. Iodine is a nonmetallic element and cannot be produced utilizing chemical synthesis. From an industrial standpoint, it can only be extracted as iodine-containing resources. While natural resources other than iodine are scarce in Japan, Iodine production in Japan covers approximately 30% of the total Iodine production in the world. Iodine demand is projected to be driven by increasing demand in X-ray contrast media, rising iodine deficiency among humans, and various uses of iodine derivatives.

As the iodine atom provides the needed radiation absorption qualities, it is a crucial component in X-ray contrast media used for in-vivo medical diagnostic procedures. Iodine is added to contrast media via electrophilic substitution of the aromatic part of this chemical structure. The iodination reagent iodine monochloride (ICl) is formed by reacting elemental iodine with chlorine. The production of iodinated contrast media necessitates the significant recovery and recirculation of spent iodine. As a result, it outperforms other contrast media.
The application of iodine in the production of X-ray contrast media is one of the primary drivers of the market studied. Since its high atomic number and density, iodine is appropriate for this use because its presence in the body increases the contrast between tissues, organs, and blood vessels with similar X-ray densities.
Adequate iodine consumption is critical for healthy growth development in humans and animals. Iodine deficiency diseases (IDD) arise when the diet is deficient in iodine. However, iodine levels in foods must be adjusted. Iodine deficiency can also impair thyroid function. In addition to this, iodine deficiency can be a significant disorder in humans and even cause severe symptoms. These symptoms include swelling in the neck, pregnancy-related issues, weight gain, and other learning difficulties.
Moreover, the US FDA regulates the addition of iodine to infant formulas and iodine to foods such as bakery products, including bread. This has fueled the demand in the market for iodine as well as increased its consumption as a necessary mineral in various food items such as dairy products (milk, yogurt, and cheese), products from grains such as cereals and bread, Iodine salt (which is readily available in countries such as United States, India and many more), seaweed and other seafood, etc. Such factors are driving the consumption of iodine during the forecast period.
Some of the clinical features of acute Iodine toxicity include gastrointestinal disturbance (vomiting and diarrhea), metabolic acidosis, seizure, stupor, delirium, and collapse. Sensitivity reactions, such as iodide mumps, iododerma, and iodide fever, may also occur following treatment with Iodine-containing drugs or radiographic contrast media.
In humans, deaths (usually within 48 hours) have occurred from iodine ingested in tinctures at doses ranging from 1,200 to 9,500 mg (17–120 mg/kg). Iodine-induced hypothyroidism in sensitive populations, including fetuses, newborn infants, and individuals who have thyroiditis, has the potential to produce neurological effects.
Reproductive and developmental toxicity: Chronic exposure to excess iodine has been shown to disrupt the reproductive function, secondary to thyroid gland dysfunction, including inducing changes in the menstrual cycle, such as menorrhagia (excessive uterine bleeding) and anovulation (no ovulation); spontaneous abortions, stillbirths, and premature births have also been associated with hypothyroidism. Therefore, the elements described above are likely to impact the iodine market during the forecast period.
Iodine is a powerful biocidal agent for bacteria, fungus, yeasts, viruses, spores, and protozoan parasites. It is the only element in the periodic table that can eliminate germs without contaminating the environment. Iodine-rich compounds, in which iodine is firmly linked as a C–I or I–O moiety in molecules, have been found as one the most promising energetic biocidal chemicals. In the disintegration or explosion of Iodine-rich compounds, gaseous products containing substantial amounts of Iodine or Iodine-containing components as potent biocides are emitted.
Because of the detonation pressure, the Iodine species are distributed over a large area, significantly improving the system's efficacy and requiring considerably less effort than traditional biocidal methods. The commercially available tetraiodomethane and tetraiodoethene, which possess amazing iodine content, also have the disadvantages of volatility, light sensitivity, and chemically reactivity. Therefore, they are not suitable for use directly as biocidal agents.
Owing to the properties of iodine, there is a massive opportunity for strategies for synthesizing active iodine-rich compounds while maintaining the maximum iodine content with concomitant stability and routes for the synthesis of oxygen-containing iodine-rich compounds to improve the oxygen balance and achieve both high-energy and high-iodine content. Hence there is a scope for the design and syntheses of new iodine-rich compounds and a route for developing more efficient and safer iodine-rich anti-biological warfare agents of the future.
