Use

Pyrimidine is widely used as pharmaceutical raw materials for the production of vitamin B, sulfadiazine, sulfadimidine, sulfamonomethoxine pyrimidine; pesticide raw materials, such as diazinon, pyrimidinol, blasticidin, bromacil, rumacil, crimidine, dodemorph, dimethirimol, ethirimol, bupirimate, pirazinon, pirimicarb, primicid, pirimiphos-methyl, polyoxin, pyramat, Pirimiphos-ethyl, etrimfos, triarimol, fenarimol and uracil, etc.; dye raw materials, for example, dyes with trihalogenated pyrimidine nucleus can react well with fiber and as reactive dyes, they have attracted people's attention. It can be used as pharmaceutical intermediates, raw materials such as photosensitive agent.
