● Siv: 1,3-Dimethylbarbituric acid yog siv los ua ib qho catalyst nyob rau hauv Knoevenagel condensation ntawm ib tug series ntawm aromatic aldehydes.Nws kuj tseem siv rau hauv kev sib txuas ntawm 5-aryl-6-(alkyl- lossis aryl-amino)-1,3-dimethylfuro [2,3-d] pyrimidine derivatives thiab enantioselective synthesis ntawm isochromene pyrimidinedione derivatives.1,3-Dimethyl Barbituric Acid (Urapidil Impurity 4) yog derivative ntawm Barbituric acid.Tag nrho cov barbituric acid derivatives uas tau tshaj tawm hais tias tau hais tawm hypnotic kev ua si yog disubstituted nyob rau hauv 5-txoj hauj lwm.
1,3-Dimethylbarbituric acid, tseem hu ua barbital, yog cov tshuaj sib xyaw nrog cov mis molecular C6H8N2O3.Nws yog ib qho dawb crystalline hmoov uas feem ntau yog siv los ua sedative thiab hypnotic tshuaj.Nws belongs rau cov chav kawm ntawm cov tshuaj hu ua barbiturates.Barbital ua hauj lwm los ntawm kev nyuaj siab lub hauv paus paj hlwb, ua sedative thiab hypnotic teebmeem.Nws feem ntau yog siv los kho insomnia thiab ntxhov siab vim.Txawm li cas los xij, vim nws muaj peev xwm rau kev quav tshuaj thiab kev siv ntau dhau, nws siv tau poob qis hauv xyoo tas los no, thiab tam sim no nws yog siv hauv cov tshuaj kho tsiaj.
