Qi, Zhengjian et al. published their research in Dongnan Daxue Xuebao, Ziran Kexueban in 2004 | CAS: 1552-42-7

Crystal violet lactone (cas: 1552-42-7) belongs to benzofurans derivatives. Many natural or synthetic compounds containing benzofuran skeletons have been found to possess remarkable activity as agrochemicals and pharmaceuticals. In nature, benzofurans have occupied an important role among the plant phenols & several pharmacologically active compounds.Application In Synthesis of Crystal violet lactone

Analysis for intermediate and by-product of crystal violet lactone with IR and NMR was written by Qi, Zhengjian;Xu, Jiang. And the article was included in Dongnan Daxue Xuebao, Ziran Kexueban in 2004.Application In Synthesis of Crystal violet lactone This article mentions the following:

The anal. of tri(p-dimethylaminophenyl)benzoic acid and trip-dimethylaminophenyl) methane with IR and NMR is described. They are intermediate and byproduct of crystal violet lactone (CVL) while it was synthesized. The main groups of both intermediate and byproduct were indicated by IR, and the mol. structures were thoroughly studied according to the chem. shift and coupling constant of 1H and 13C-NMR. Comparing with Sadder standard atlas, it is indicated that the method is scientific and reasonable. The results are useful to the research of synthesis of CVL. In the experiment, the researchers used many compounds, for example, Crystal violet lactone (cas: 1552-42-7Application In Synthesis of Crystal violet lactone).
