Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No studies of abiotic degradation are available for MV 31. We have proposed waiving of hydrolysis testing due to low water solubility (145 µg/L at 23 °C). With a vapor pressure of 50 hPa at 20 °C and a dimensionless Henry's Law constant of 19,300 (i.e., 469 atm∙m³/mol), MV 31 is expected to partition exclusively to the atmospheric compartment. The atmospheric reactions of MV 31 have not been studied. As a perfluorinated alkyl vinyl ether, MV 31 is subject to rearrangement forming perfluorinated acid fluorides upon exposure to ultraviolet radiation or free radicals. The structure(s) of putative acid fluoride(s) has not been determined. Perfluoroacid fluorides are hydrolytically unstable and will form the corresponding perfluorocarboxylic acids.
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.
