Dinitrochlorobenzene is an organic compound, a strong potent contact allergen that has many medical as well as laboratory uses. One dominant use of dinitrochlorobenzene has been in the treatment of alopecia areata, an autoimmune disease that can cause widespread hair loss, with hair loss on the scalp being the most concerning to patients typically. Alopecia areata, commonly known as spot baldness, causes hair to fall out in round patches due to a default in the immune system that can result in an attack on the body's own hair follicles. This condition is known to affect up to 2% of the population in America.

In the lab, dinitrochlorobenzene is often used as a substrate in enzyme activity testing. It is also used as a treatment for warts and as such typically has a cure rate of approximately eighty percent. Additionally dinitrochlorobenzene is used to gauge the relative T cell activity in patients.
