Popis: 5,7-Dihydroxy-4,8-dimethylchromen-2-one was synthesized based on methyl phloroglucinol and its spectral and physicochemical characteristics were obtained. Reactions of the newly synthesized coumarin with different diazonium salts were studied, conditions allowing selective obtaining the corresponding monoor bisazo compounds were found. The synthesized azo compounds dye nylon in the yellow-brown colors under standard coloration conditions, providing high stability of obtained colors upon exposure to physicochemical conditions.
