98% Pyrimidine CAS 289-95-2

Pyrimidine yog ib qho tseem ceeb ntawm cov organic tebchaw nyob rau hauv chav kawm ntawm heterocyclic tebchaw nrog tsawg solubility hauv dej. Nws cov qauv tshuaj yog ib lub nplhaib rau - cov tswv cuab uas muaj ob lub nitrogen atoms. Nws muaj tsawg solubility nyob rau hauv dej tab sis zoo solubility nyob rau hauv cov organic solvents xws li ethanol thiab dimethyl sulfoxide. Cov tshuaj yog lub hauv paus tsis muaj zog uas cuam tshuam nrog acids los tsim cov ntsev. Nws tuaj yeem raug oxidation tshwm sim, xws li reacting nrog concentrated nitric acid los tsim nitropyrimidine. Pyrimidine tuaj yeem raug hloov pauv cov tshuaj tiv thaiv electrophilic, xws li cov tshuaj tsw qab uas muaj ntxhiab aldehydes los tsim cov tshuaj tsw qab ethers.

1. Pyrimidine yog ib qho tseem ceeb ntawm nucleic acids. Cov hauv paus no ua lub luag haujlwm tseem ceeb hauv kev khaws cia thiab xa cov ntaub ntawv ntawm caj ces.
2. Vim nws txoj kev ua lom neeg thiab muaj ntau yam tshuaj lom neeg, pyrimidine thiab nws cov derivatives muaj ntau yam kev siv hauv tshuaj chemistry.
3. Raws li ib qho yooj yim heterocyclic compound, nws yog ib qho khoom pib lossis nruab nrab rau kev sib txuas ntawm ntau cov molecules complex. Nyob rau hauv cov organic synthesis, nws yog feem ntau siv los npaj ntau yam pyrimidine derivatives.
