Description of key information
Additional information
The substance 6-methyl-2-oxoperhydropyrimidin-4-yl urea is expected to be not stable in the environment. Due to its ready biodegradability the substance will be rapidly mineralized by microorganisms in the aquatic environment as well as in the terrestrial environment.
When released to the environment the substance is expected to mainly distribute to the aquatic compartment. This assumption is based on the water solubility (5.065 g/L ; Frischmann, 2012) and on further physico-chemical properties of the substance. As indicated by calculated values on soil adsorption potential (log Koc: 0.098, based on log Pow, KOCWIN v2.00) the substance will not adsorb to the solid phase and thus distribution to the soil compartment is not probable. Furthermore the substance is not volatile (VP: =< 0.35 Pa, Kintrup, 2012) and thus evaporation to the air is not likely. However, for indirect photodegradation in air by OH-radicals a half- life of less than 24 hours was calculated for the substance (DT50: 6.94 h, AOPWIN v1.92).
Due to its rapid degradation the bioavailability of 6-methyl-2-oxoperhydropyrimidin-4-yl urea is presumably very low and thus the substance is not expected to be taken up by organisms. Furthermore the low log Kow indicates that bioaccumulation of the substance is unlikely (log Kow: -1.34; OECD 107).
