Ethyleneurea

[simply RED]

As you know ethyleneurea(cyclo -CH2-CH2-NH-CO-NH-) is the precursor for EDNA.
EDNA is made by nitrating ethyleneurea with H2SO4, HNO3 or HNO3, acetic anhydride and then hydrolising of the final product.
Very much chemical suppliers sell ethyleneurea and it's very cheap, so my question is:
What are the physical properties of ethyleneurea, is it toxic and carcinogenic. Somewhere in the web was typed it is?
Do you know are EDNA and MEDINA toxic?

That reminds me, I was meant to be getting an EU sample, but it never arrived :mad: . And I was looking forward to playing with EDNA :(.

EU: also called 2-Imidazolidone. I did a quick search and couldn't actually find any MSDS for it, only alkyl derivatives etc. I did find: "2-imidazolidone (also known as ethyleneurea) induces tumors in combination with nitrate and causes genetic damage."
