EC number: 701-162-1
CAS number: -
Direct photolysis in air, water and soil
The UV Spectrum of the registration substance shows a small shoulder at
>290 nm so that direct photolysis may occur.
Indirect photolysis in air, water and soil
Indirect photolysis via OH radical or ozone reaction is fast (Half-life
0.5 -1d). This means indirect photolysis is a possible fate pathway.
N-Methyl acetamide, CAS No. 79-16-3 has a half-life of 38000 years (pH7,
25 deg C, Reference: Mabey, W. and Mill, T. 1978. Critical Review of
Hydrolysis of Organic Compounds in Water Under Environmental Conditions.
J. Phys. Chem. Ref. Data 1978, 7(2): 383-415). Hall et al have
compared the rate of the alkaline hydrolysis of cyclic imides e.g.
N-Methyl succinimide, CAS No. 1121-07-9 with the rate measured for the
corresponding acyclic substance e.g. N-Methyl acetamide. They found
equal or slower hydrolysis for the cyclic compound. The registration
substance contains a (cyclic) N-alkyl succinimide moiety and it can be
concluded that hydrolysis under environmental conditions (pH 4 to 9, 12
deg C) is comparable to N-Methyl acetamide mentioned before. Because of
this extremely long half-life a hydrolysis study is not warranted.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
