| Application: | High-purity iodine has a variety of uses in the pharmaceutical, chemical, and electronic industries. In the semiconductor and electronics industry, high-purity iodine is used in the production of semiconductors, where it is used as a dopant to create p-type semiconductors and in the production of LCD displays. In the life sciences industry, high-purity iodine is used to create X-ray contrast agents, which are used to enhance the visibility of specific organs in medical imaging. Iodine is also used as a disinfectant, antifungal agent, and antiseptic in various medical applications. Its unique properties make it an important element in various high-tech applications where its high purity is essential. |
| Features and Benefits: | Our 99.99% pure iodine is useful in the pharmaceutical, chemical, and electronic industries where purity matters most. ✔ Consistent quality ✔ High-purity ✔ Available to Scale Up: Bulk and Pilot Scale |
| General description: | Iodine is a dark grey solid that sublimates into a violet gas. For a solid, molecular iodine has a high vapor pressure (0.31 mmHg at 25 °C). Chemically, iodine is electrophilic and can participate in electrophilic substitution reactions, such as the iodination of organic compounds. This electrophilic behavior is due to the high electronegativity of iodine and its large size, which make it a relatively weak oxidizing agent. Our high-purity iodine is synthesized to have fewer than 100 ppm of trace metals impurities. |
