5 Ways Iodine Derivatives Are Used Everyday
Sep 18 2015

Iodine is one of the scarcest non-metallic elements found on Earth, but it is actually found in trace amounts in objects all around us. Iodine derivatives are used in and to create objects that you interact with every single day. Read on to learn more about how iodine derivatives are used to create the things we use on a daily basis.

Uses for Iodine Derivatives

1. LCD Screens

LCD screens — or liquid crystal display screens — are comprised of liquid crystals that are activated through an electric current. LCDs can display “low-information” content such as digits (like you might see on a clock) or more complex and arbitrary images (like you might see on a computer screen.)

Iodine is a large factor in the manufacturing of LCD screens as it is used to dope the plastic polarizing screens. Without iodine doping, the light from the backlight wouldn’t all be polarized in the same direction, and the LCD screen wouldn’t work.

You probably have several LCD screens throughout your home, office, or even in your car. LCD screens are used for a variety of things such as:

•Digital watches
•Laptop computers
•TV screens
•Digital cameras

2. Animal Feed

Over 95% of the iodine found in the human body is stored in the thyroid gland. We need iodine for our brains and nervous systems to develop normally. In order to ensure that the population is consuming enough iodine, it has been introduced into animal feed to improve the supply to human diets.

By introducing iodine into animal feed for animals such as cattle, pigs and poultry, humans are able to absorb iodine from eating these food producing animals.

3. Human Food

In conjunction with consuming iodine through the animal byproducts we eat, we also take in a lot of iodine through a very simple seasoning. When you want to liven up a dish with table salt, you are actually adding iodized salt.

When people do not get enough iodine from their diets, iodine deficiency disorders (IDD) result. The World Health Organization says that IDD is the most prevalent and preventable cause of brain damage. IDDs are a serious concern for pregnant women and developing children. Other effects of IDD are goiter, a swelling of the front of the neck that is due to enlargement of the thyroid gland, abnormal physical development and reproductive loss.

4. Nylon 6 & Nylon 6.6

Potassium and cuprous iodides are used as heat stabilizing agents in the manufacturing of Nylon 6 and Nylon 6.6. These fibers are mainly used in tire production, and these polymers help keep the tires cool. Tires on a light vehicle could reach a temperature of 120 degrees Celsius, but using potassium and cuprious iodides allows stabilization up to 170 degrees Celsius. These iodides keep the chemical chains from cracking so that the tires last longer.

5. Pharmaceuticals

Iodine is used in the pharmaceutical industry as an active ingredient in many types of drugs like:

•Coronary vasodilators
•Neuromuscular blocking agents

Organic iodine derivatives also serve as many intermediate molecules in the synthesis of pharmaceutical compounds like:

•UV-B absorbers in sunblock
