Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
HCFC 122a is a liquid with a relatively high tendency to volatize to the atmosphere.
The lifetime in the atmosphere has been estimated to be 3.4 years.
As other hydrochlorofluorocarbons, although not as stable and therefore not persistent in the atmosphere as CFCs, HCFC 122a is expected to diffuse in the stratosphere where the reaction with the ozone by photochemically-produced chlorine radicals can occurr, resulting in the ozone layer depletion. For this reason, according to Regulation (EU) 1272/2008, it has been classified as “Hazardous to the Ozone Layer 1”.
The contribute to Global Warming has been estimate as following:
GWP at 20 years = 770
GWP at 100 years = 240
GWP at 500 years = 71
Basing on experimental results, HCFC 122a is not expected to be readily biodegradable in water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
