Analytics and Application of Biologically Active Pentacoordinate Electrostatically Stabilized Silanates

The objective of this study was to synthesize information on the analytics, using two separation techniques, and the application of electrostatically stabilized silanate derivatives. They are biologically active, water-soluble, hydrolytically stable and biodegradable. Some of these compounds are used as plant growth regulators, while others, with higher molecular mass and lower electrophoretic mobility, are used in the form of terminating electrolytes in isotachophoresis, which is regarded as one of the green chemistry techniques. Two compounds were successfully used in the form of terminating electrolyte solutions, i.e. 4,4'-bis{1-(perhydroazepiniomethyl)[spirobi(1-sila-2,5-dioxacyclopentane-3-on)]at}, and 4,4'-bis{1-[(N,N-dimethyl)aminiomethyl]spirobi(1-sila-2,5-dioxacyclopentane-3-on)at} to isolate organic ionic substances with high molecular mass, e.g. derivatives of quinoline, stilbene and electrostatically stabilized silanates (ES-silanates). Establishing the best conditions for the analysis of these derivatives extends the possibilities of conducting research on their biological activity and miscellaneous applications. Furthermore, the terminating electrolytes used in the form of solutions of electrostatically stabilized silanates allow the analysis of both cationic and anionic forms.
