, they are considered compatible. So, incompatible is vice versa. Chemical compatibility is important when choosing materials for chemical storage or reactions, so that the vessel and other apparatus will not be damaged by its contents. For purposes of

chemical storage Chemical storage is the storage of controlled substances or hazardous materials in chemical stores, chemical storage cabinets, or similar devices. Chemical storage devices are usually present where a workplace requires the use of non-hazardous ...

, chemicals that are incompatible should not be stored together so that any leak will not cause an even more dangerous situation by reacting after leaking. In addition, chemical compatibility refers to the container material being acceptable to store the chemical or for a tool or object that comes in contact with a chemical to not degrade. For example, when stirring a chemical the stirrer must be stable in the chemical that is being stirred. Because of this many companies publish

polymer tools used for chemical experiments must be chosen to ensure chemical compatibility with care. Chemical compatibility is also important when choosing among different chemicals that have similar purposes. For example,
