● Hoʻohana: 1,3-Dimethylbarbituric acid i hoʻohana ʻia ma ke ʻano he catalyst i ka condensation Knoevenagel o ke ʻano o nā aldehydes aromatic.Hoʻohana ʻia ia i ka synthesis o 5-aryl-6-(alkyl- or aryl-amino) -1,3-dimethylfuro [2,3-d] pyrimidine derivatives a me enantioselective synthesis o isochromene pyrimidinedione derivatives.ʻO 1,3-Dimethyl Barbituric Acid (Urapidil Impurity 4) he mea ia o ka waika Barbituric.ʻO nā mea hoʻoheheʻe barbituric a pau i hōʻike ʻia i haʻi ʻia i ka hana hypnotic ua hoʻopau ʻia ma ke kūlana 5.
ʻO ka 1,3-Dimethylbarbituric acid, ka mea i ʻike ʻia he barbital, he pūhui kemika me ke ʻano molekala C6H8N2O3.ʻO ia ka pauka crystalline keʻokeʻo i hoʻohana mau ʻia e like me ka lāʻau hoʻomaha a me ka hypnotic.Aia ia i ka papa o nā lāʻau lapaʻau i kapa ʻia ʻo barbiturates. Hana ʻo Barbital ma ka hoʻohaʻahaʻa ʻana i ka ʻōnaehana nerve waena, hana i nā hopena sedative a hypnotic.Hoʻohana maʻamau ia e mālama i ka insomnia a me ka hopohopo.Eia nō naʻe, ma muli o kona hiki ke hoʻohui a me ka overdose, ua emi ka hoʻohana ʻana i nā makahiki i hala iho nei, a ua hoʻohana mua ʻia i ka lāʻau lapaʻau holoholona.
