Sažetak
Chemistry of vitamin B6 was intensively investigated for nearly a century, which is understandable given the importance of the life processes in the body. In recent years research has focused on the synthesis and spectroscopic studies of new analogs of vitamin B6, which can be used in human medicine for recovery of the organism poisoning by organophosphorus compounds. UV/VIS absorption spectra of the synthesized derivatives of vitamin B6 were recorded in aqueous solutions of different pH values. Absorption spectra of aqueous solutions of the test compounds changed with changing the pH of the solution. In acidic medium there are two peaks, one at about 279-293 nm and the other at 330 nm. By increasing the pH the second peak is lost, and the first moves at about 270-274 nm with the emergence of a new peak at about 378-380 nm.
