One of the important representatives of metallocenes is the practical significance of biologically active compounds derived from ferrocene in the chemical industry, medicine, pharmacology, as well as the synthesis of o-ferrocenylbenzoic acid with amygdalin ([(6-O-β-D-glucopyranosyl-4-O-(o-ferrocenylbenzoyl)β-D-glucopyranosyl)oxy](phenyl)acetonitrile), reaction with monomethylolurea and reaction product of 1-2-carboxyperphenyl)-1'-N-methyloxyferrocenylamide IR, mass spectroscopic analysis, data on study of the biological activity of its water-soluble salts.
