The spectral characteristics of alkaline hydrolysis product kalimin 60 N, and its stability for different pH were studied. Chromatographic mobility of 1-methyl-3-pyridone was studied by the method of the reversed thin-layer chromatography. The optimal conditions (pH, wavelength) for a quantitative determination of 1-methyl-3-pyridone in a solution by the spectrophotometric method were determined. We found out that 1-methyl-3-pyridone is resistant to oxidation by atmospheric oxygen during a period that is necessary for the isolation and cleaning while extracting metabolite from the model mixtures.
Изучены спектральные характеристики продукта щелочного гидролиза калимина 60 Н, а также его стабильность при различных значениях рН. Изучена хроматографическая подвижность 1-метил-3-пиридона методом обращеннофазовой тонкослойной хроматографии. Определены оптимальные условия (рН, длина волны) для количественного определения 1-метил-3-пиридона в растворе спектрофотометрическим методом. Установлено, что 1-метил-3-пиридон устойчив к окислению кислородом воздуха в течение времени, необходимом для изолирования и очистки при извлечении метаболита из модельных смесей.
