1-甲基-3,5-二苯基吡唑是四价吡唑盐(鎓盐)类除草剂(如野燕枯)的重要中间体。本品易于提纯且较稳定。在色谱分析中用作内标物,最近的研究表明,它可以和某些过渡金属氯化物如CuCl_2、CoCl_2等作用形成络合物,对这种络合物的初步研究表明,它对某些吡唑啉的脱氢有催化作用,有可能成为很重要的化学试剂。有关它的合成方法,文献上报导得很多,大都采用先合成3,5-二苯基吡唑,再甲基化的方法,即由查耳酮与水合肼反应生成3,5-二苯基吡唑啉,再经脱氢得3,5-二苯基吡唑,甲基化后得1-甲基-3,5-二苯基吡唑。也可用
1-Methyl-3,5-diphenylpyrazole is an important intermediate for quaternary tetrazolium (onium salt) herbicides (such as wild oat). This product is easy to purify and more stable. It is used as an internal standard in chromatographic analysis. Recent studies have shown that it can form complexes with some transition metal chlorides such as CuCl 2 and CoCl 2. A preliminary study of this complex shows that it has some effects on some The dehydrogenation of pyrazoline has the catalytic effect and may become a very important chemical reagent. About its synthesis method, the literature reported a lot, mostly using the first synthesis of 3,5-diphenylpyrazole, remethylation method, that is, by chalcone and hydrazine hydrate reaction of 3,5-diphenyl Pyrazoline, dehydrogenation and then 3,5-diphenylpyrazole, methylation to give 1-methyl-3,5-diphenylpyrazole.
