Dimethoate
Is there any experiments that could be safely done with dimethoate? I know its an organophosphate so requires the full arsenal of PPE to be around,
but is there any science I can do with it, without killing myself?

Are you talking about pure dimethoate or a pesticide with roughly 40% dimethoate content? In the later case the isolation could be your first
challenge.
I can't think of too much chemistry starting from such a "complicated" substance apart from alkaline hydrolysis. That process could yield methanol,
thioglycolic acid (salt), methylamine and thiophosphate salt, or phosphate salt.
I don't know the LD50 of the pure substance but dimethoate formulations (at least those I heard about) has it in the range of 400-600 mg/kg
oral. These are considered poisonous but not too extremely, there were much worse insecticides in circulation a few years ago. (At least here in the
EU, your milleage may vary.)

Thanks, I dont think Im going to use it than. Its the 40% stuff. Ill save it for the leaf miners that like a birch tree I have on my property.
