In context of stability in the environment,
only information about hydrolysis is required under REACH for
monomethylamine. The substance is stated to be thermodynamically stable
in water to hydrolysis at pH 4, 7, and 9 (Verscheuren, K., 1988). No
further information is given.
Despite information about
phototransformation in air is not mandatory, different data sources,
based on scientifically accepted calculations are available. The key
information is taken from the computer tool EPIWINv3.20 (software
AOPWINv1.92 by US-EPA) which assumes OH as sensitiser and gives an
overall rate constant of 22.2648 E-12cm³/mol*sec. Taking a 24 hour-day
into account 50 % degradation of monomethylamine will occur within about
