===Interstellar detections===
Chloromethane has been detected in the low-mass Class 0 protostellar binary, [[IRAS 16293-2422|IRAS 16293'''–'''2422]], using the [[Atacama Large Millimeter Array]] (ALMA). It was also detected in the comet [[67P/Churyumov–Gerasimenko]] (67P/C-G) using the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) instrument on the [[Rosetta (spacecraft)|Rosetta]] spacecraft.<ref>{{Cite web | url=https://www.eso.org/public/images/eso1732e/ |title = ALMA and Rosetta Detect Freon-40 in Space}}</ref> The detections reveal that chloromethane can be formed in [[Star forming region|star-forming regions]] before planets or life is formed.{{cn|date=October 2023}}
