Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere, formamide, which has a vapor pressure of 0.08 hPa at 25 °C, is expected to exist solely as a vapor in the ambient atmosphere.
Vapor-phase formamide is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 8 days, calculated from its rate constant of 2.0E-12 cm³/molecule*sec at 25 °C determined using a structure estimation method according to Bidleman (1988).
Key value for chemical safety assessment
Additional information
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.
