EC number: 204-137-9
CAS number: 116-37-0
The substance is hydrolytically stable at
pH 4, 7 and 9. The half-life time at 25°C is > 1 year for pH 4, 7 and 9
(OECD 111, preliminary test).
Two ready biodegradation tests under
OECD 301F and 301D exist and conclude to “not readily biodegradable”.
Under the conditions of the closed
bottle test (OECD 301D), 15% after 28 days were reached. There are
indications that the substance is ultimately biodegradable (60% after 98
Moreover, under the Manometric
Respirometry Test (OECD 301F), the pass level of > 60% ThOD
of biodegradation is reached within 28 days. The ready biodegradation
levels of the substance were 60.3% at day 28 and 64.9% at day 43.
Considering that 60% of ultimate
biodegradation (complete mineralisation to C02) was reached within the
28-day period of the OECD 301F test, the substance is readily
biodegradable but failing the 10 days windows criteria. Therefore it is
possible to conclude that the substance is not persistent under relevant
Three test substance related peaks were
observed in the HPLC screening test according to OECD 121. The resulting
Koc and log Koc values of the substance at neutral pH are in the range
1800 -2700 and 3.26 -3.44, respectively. This indicates that when the
substance would end up in the soil compartment it will be immobile there.
