EC number: 237-438-9
CAS number: 13784-51-5
At pH 7 2,4 -pentanedione peroxide is rather
stable with a half-life of 200 hours at 20 °C. At pH 9 hydrolysis is
much faster with a half-life of 12.5 hours at 20 °C.
A ready biodegradability test is also
available. The conclusion from that study is that 2,4 -Pentanedione
peroxide is readily biodegradable.
From these two findings it can be concluded
that 2,4 -pentanedione peroxide is not persistent.
Bioaccumulation was not tested as 2,4
-Pentanedione peroxide has a low log Kow of 1.1, therefore
bioaccumulation is not expected.
Adsorption onto soil and sediment is not
expected either due to the low log Kow, ready biodegradability and high
