This is a list of inorganic and organic reagents commonly used in chemistry.


Reagents are "substances or compounds that are added to a system in order to bring about a chemical reaction or are added to see if a reaction occurs."[1] Some reagents are just a single element. However, most processes require reagents made of chemical compounds. Some of the most common ones are listed below.
