It is designated as an ideal replacement for perhalogenated chlorofluorocarbons because it is 1/10 the ozone depleting effect of CFC-113.

HCFC-141b is a widely used non-perhalogenated chlorofluorocarbons. Although its damage to the ozone layer has been greatly reduced compared to fully halogenated chlorofluorocarbons, it will still cause irreversible damage to the ozone layer. As a result, the world is gradually reducing its use.

According to the "Montreal Agreement", the use period of HCFC-141b in developed countries is until 2010, and the United States, Japan and other countries have already restricted the use in advance. In developing countries such as China, the use period can be up to 2040, and China has promised to advance it to 2030

Its azeotrope with methanol, 141b MA, was successfully developed mainly for the electronics industry. This feature is also suitable for cleaning and degreasing of various metal and plastic precision components and optical components. It is designed to improve the cleaning power of polar contaminants and improve the volatilization characteristics of HCFC-141b solutions.
