Despite its various advantages, 113 is chemically particularly stable, has a long lifetime in the troposphere, and diffuses into the stratosphere, where it is decomposed by sunlight and generates chlorine radicals, which are absorbed into the ozone. Since it is said that it causes a chain reaction and destroys the ozone layer, restrictions on its use have been implemented. Therefore, in place of the conventional R113, an active search is being made for alternative solvents that are less likely to destroy the ozone layer.
