It is one of the three isomers of dichlorofluoroethane. It belongs to the hydrochlorofluorocarbon (HCFC) family of man-made compounds that contribute significantly to both ozone depletion and global warming when released into the environment. Physiochemical properties 1,1-Dichloro-1-fluoroethane can be a non-flammable, colourless liquid under room-temperature atmospheric conditions. The compound is very volatile with a boiling point of 32°C.http://ashrae.org/File%20Library/docLib/Public/20070613_342004_d_j_l_m_t_only.pdf Addenda d, j, l, m, and t to ANSI/ASHRAE Standard 34-2004 2007-03-03 ANSI/ASHRAE Standard 34-2004, Designation and Safety Classification of Refrigerants American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc.

Production and use 1,1-Dichloro-1-fluoroethane is mainly used as a solvent and foam blowing agent under the names R-141b and HCFC-141b. It is a class 2 ozone depleting substance undergoing a global phaseout from production and use under the Montreal Protocol since the late 1990s. It is being replaced by HFCs within some applications.https://ec.europa.eu/clima/sites/clima/files/docs/0007/icf_hcfc_background_doc_en.pdf Overview of HCFC Consumption and Available Alternatives For Article 5 Countries ICF International 2008 2021-02-12 Environmental effects thumb|left|upright=1.3|Growth of HCFC-141b in Earth's atmosphere since year 1993.https://www.esrl.noaa.gov/gmd/hats/gases/HCFC141b.html HCFC-141b NOAA Earth System Research Laboratories/Global Monitoring Division 2021-02-12 thumb|left|HCFC-141b measured by the Advanced Global Atmospheric Gases Experiment (AGAGE) in the lower atmosphere (troposphere) at stations around the world.

Halocarbon Scenarios, Ozone Depletion Potentials, and Global Warming Potentials This is low compared to the ODP=1 of trichlorofluoromethane (CFC-11, R-11), which also grew about ten times more abundant in the atmosphere prior to introduction of HFC-141b and subsequent adoption of the Montreal Protocol. HFC-141b is also a minor but potent greenhouse gas. It has an estimated lifetime of about 10 years and a 100-year global warming potential ranging 725 to 2500.https://www.ipcc.ch/report/ar5/wg1/ Chapter 8 AR5 Climate Change 2013: The Physical Science Basis 731Refrigerants - Environmental Properties http://www.engineeringtoolbox.com/Refrigerants-Environment-Properties-d_1220.html The Engineering ToolBox 2016-09-12 This compares to the GWP=1 of carbon dioxide, which had a much greater atmospheric concentration near 400 parts per million in year 2020.
