● Whakamahinga: Ka whakamahia te waikawa 1,3-Dimethylbarbituric hei whakakorikori i roto i te Knoevenagel condensation o te raupapa o te aldehydes kakara.Ka whakamahia ano hoki i roto i te whakahiatotanga o te 5-aryl-6-(alkyl- or aryl-amino) -1,3-dimethylfuro [2,3-d] pyrimidine derivatives me te enantioselective synthesis o isochromene pyrimidinedione derivatives.Ko te 1,3-Dimethyl Barbituric Acid (Urapidil Impurity 4) he hua o te waikawa Barbituric.Ko nga hua o te waikawa barbituric katoa i kiihia he mahi hypnotic ka whakakorehia ki te waahi-5.
Ko te waikawa 1,3-Dimethylbarbituric, e mohiotia ana ko te barbital, he pūhui matū me te tātai rāpoi C6H8N2O3.He paura tioata ma e whakamahia nuitia ana hei rongoa whakamaoriori me te rongoa hypnotic.No te karaehe o nga raau taero e mohiotia ana ko te barbiturates.Ka mahi a Barbital ma te whakapouri i te punaha o te puku, ka whakaputa i nga hua whakakorikori me te hypnotic.I te nuinga o te waa ka whakamahia ki te rongoa i te ohoroa me te awangawanga.Heoi ano, na te kaha mo te waranga me te nui o te horopeta, kua heke te whakamahinga i nga tau tata nei, a kei te whakamahia nuitia inaianei ki nga rongoa kararehe.
