must first be soluble in water and be a stable compound in an aqueous medium. The synthesis of 
such substances, on the other hand, requires the solution of specific problems. Sodium salt of o-
carboxybenzoilferrocene (Ferrocerone), synthesized by A.N. Nesmeyanov and a group of 
scientists, sodium salt of p-ferrocenylphenol (Ferand), potassium salt (ferrostimulator-1), other 
aromatic derivatives (ferrostimulator-2, ferrostimulator-3) synthesized by I.R. Askarov and his 
students are among the compounds synthesized and put into practice on the basis of ferrocene,
can be taken as an example [10]. Ferrocene and its derivatives are also being studied in a number 
of developed countries, including Russia, the United States, Germany and China. They 
synthesize aliphatic, aromatic compounds of ferrocene and study their physical, chemical, 
physicochemical properties. 
The biological activity of some compounds of ferrocene has been determined. 
Biostimulatory property is the process of accelerating their growth and development by affecting 
cells, tissues and the body. 
There are several ways to study the biostimulatory properties. The biological activity of 
newly obtained substances is determined by testing in animals and plants. 
Ferrocene and its derivatives are the most important compounds among organometallic 
compounds. Therefore, today ferrocene derivatives are widely used in medicine in the treatment 
of anemia, colds, surgery. In agriculture, they are used as biologically active compounds in the 
germination, growth and development of plants and increase their productivity. 
Ferrostimulators were synthesized and put into practice in the scientific laboratory 
"Classification and certification of goods on the basis of chemical composition" at Andijan State 
University. Ferrostimulants are biologically active substances containing the ferrocenyl group. 
Ferrostimulants, in addition to accelerating the growth rate of the plant, have a positive effect on 
seed germination and overall development of the plant, and increase productivity by 3-4 c /ha. 
The physiological activity of ferrocene derivatives is determined by the specific structure 
of its molecule and the properties of certain functional groups in the derivatives obtained as a 
result of arylation, alkylation, acylation, condensation reactions. Urea is a mineral fertilizer that 
has a positive effect on the growth and development of plants. Urea contains four active 
hydrogen atoms. Therefore, it reacts with formaldehyde to form mono-, di-, tri- and tetra-
exchange compounds. Synthesis of new compounds based on ferrocene and urea and thiourea 
derivatives is important [11]. 
RESULTS. 
We have developed a technological scheme for the synthesis of the 
biostimulant ADUMAX. Ferphenol, Ferben-potassium, Ferben-sodium drugs were synthesized 
on the basis of this technological scheme.

Given 
the 
multifaceted 
advantages of liquid nitrogen fertilizers 
and the growing demand, we aimed to create liquid nitrogen fertilizers containing ferrocene 
derivatives and test them in practice.
