FIELD: production of a salt of branched oligohexamethylenguanidine (OHMG).
SUBSTANCE: present invention relates to variants of methods for producing a salt of branched oligohexamethylenguanidine (OHMG). The salt of branched oligohexamethylenguanidine has the general formula (I):
(I),
where R represents 
or 
, and n1, n2, and n3 are equal to 1-3, z is 0.15-1.10 with an average molecular weight of Mn in the range from 850 to 1500 Da, selected from hydrochloride, hydrosuccinate, hydrocitrate, hydrosalicylate, hydrosulfosalicylate, having a purity sufficient for its use as a pharmaceutical substance.
EFFECT: production of branched oligohexamethylenguanidine salts with reproducible molecular characteristics and physico-chemical properties and a reduced content of ballast and toxic substances and a degree of purity sufficient for their use as a pharmaceutical substance.
