2-(3,5-dioxo-[1,2,4]-triazine-1-yl)-acetic acid semihydrate

摘要

The invention relates to a complexones class, namely to a cyclic product on base of semicarbaziddiacetic acid, which may be applied in the capacity of remedy for extraction of incorporated metals from the organism. Summary of the invention consists in that it is synthesized a new complexone 2-(3,5-dioxo-[1,2,4]-triazine-1-yl)-acetic acid semihydrate of the formula:<CHFORM>wherein it is formed an uncommon combination of links with the formation of triazine cycle, at the expense of proton detachment from the NH2 group and of OH??ion from one acetate branch of the semicarbaziddiacetic acid.Claims: 1Fig.: 2
