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. Introduction of benzofurans in organic synthesis, particularly drug synthesis, involves generally the use of their metalated species as nucleophiles in addition reactions or in metal-catalysed cross-coupling reactions.Application In Synthesis of Crystal violet lactone

Fabrication of visual textile temperature indicators based on reversible thermochromic fibers was written by Zhang, Yangkai;Hu, Zexu;Xiang, Hengxue;Zhai, Gongxun;Zhu, Meifang. And the article was included in Dyes and Pigments in 2019.Application In Synthesis of Crystal violet lactone This article mentions the following:

Human body signals detection functions in fibers such as visual temperature indicator, are important aspects in future development of satisfying the warmth and comfortableness of conventional textile fibers. A series of reversible thermochromic fibers (VTFs), where thermochromic microcapsules and polypropylene (PP) was used as color indicator and polymer fiber matrix, resp., were prepared via melt spinning in this paper. The temperature-color response behaviors of VTFs were investigated in detail. The SEM images of cross section of VTFs showed that PP was an excellent matrix for the dispersion of thermochromic microcapsules and no aggregation occurred. The results of color measuring and matching indicated that VTFs exhibited various colors of red, purple and blue depending on the mass ratio of the red function and blue function microcapsules. Moreover, when the ambient temperature changed between 5 °C and 35 °C, the color of VTFs could fade and recover in a short time, and this kind of VTFs displayed excellent performance stability after 60 temperature cycles. In the experiment, the researchers used many compounds, for example, Crystal violet lactone (cas: 1552-42-7Application In Synthesis of Crystal violet lactone).
