ChEBI: 2-(dimethylamino)-5,6-dimethylpyrimidin-4-ol is an aminopyrimidine and a pyrimidone.

Photolysis of solutions of methylene blue and 2- dimethylamino-5,6-dimethylpyrimidin-4-ol in CDCl3 and d6-acetone in an NMR sample tube with irradiation from a 600 W tungsten ? halogen lamp while dry oxygen is bubbled through the solution202 Not a pesticide: hydrolysis product of pirimicarb fungicide Photolysis of solutions of methylene blue and 2- dimethylamino-5,6-dimethylpyrimidin-4-ol gives the photolysis product of the zwitterion which is stable in solution at ambient temperature. It is suggested that, when the zwitterion is in contact with the silica gel of the TLC plate, it gives some degradation products, and if the zwitterion were to be formed in the environment on photooxidation of the pyrimidinol, and in contact with plant and soil surfaces, then it would react or break down to give further products.
