Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Environmental Abiotic Degradation: The rate constant for the vapor-phase reaction of isoamyl acetate with photochemically-produced hydroxyl radicals has been estimated as 6.0X10-12 cu cm/molecule-sec at 25 deg C (*Meylan and Howard). This corresponds to an atmospheric half-life of about 64 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm (*Meyland and Howard, SRC).
