Hydroxyl radicals are highly reactive chemical species with the formula OH. They are characterized by a single unpaired electron, making them free radicals. This unpaired electron causes them to readily seek out and react with other molecules to achieve stability, often by abstracting an atom or accepting an electron. Hydroxyl radicals are extremely short-lived and have a very high oxidation potential.

These radicals play a significant role in various chemical and biological processes. In atmospheric chemistry, they are crucial for the degradation of many pollutants and the formation of ozone. In environmental science, they are involved in the breakdown of organic matter in water and soil. Biologically, hydroxyl radicals can be generated during normal metabolic processes, such as through the action of certain enzymes. However, excessive production of hydroxyl radicals in biological systems can lead to oxidative stress, damaging cellular components like DNA, proteins, and lipids. This damage is implicated in aging and various diseases.

Methods for detecting and quantifying hydroxyl radicals are often indirect due to their fleeting nature, typically involving trapping them with specific molecules that form more stable products that can then be analyzed. Their reactivity makes them powerful oxidizing agents and important intermediates in many chemical transformations.
