Additional information

1,3-bis(3-methyl-2,5-dioxo-1H-pyrrolinylmethyl)benzene showed hydrolysis at all pH values at 50 °C, rates being relatively low at low pH and very high at high pH conditions. Preliminary toxicity to bacteria was tested in which no respiration inhibition and biodegredation was observed.

The adsorption coefficient (Koc) of 1,3-Bis(3-methyl-2,5-dioxo-1H-pyrrolinylmethyl)benzene was determined at log Koc = 2.8. at 25 °C.
