Liu, Jidan et al. published new progress in experiments with the help of cas: 99-36-5

Methyl 3-methylbenzoate (cas: 99-36-5) is a common ester.Esters are common in organic chemistry and biological materials, and often have a pleasant characteristic, fruity odor. This leads to their extensive use in the fragrance and flavor industry. Ester bonds are also found in many polymers.Category: esters-buliding-blocks

Liu, Jidan;Xu, Erjie;Jiang, Jinyuan;Huang, Zeng;Zheng, Liyao;Liu, Zhao-Qing published 《Copper-mediated tandem ring-opening/cyclization reactions of cyclopropanols with aryldiazonium salts: synthesis of N-arylpyrazoles》 in 2020. The article was appeared in 《Chemical Communications (Cambridge, United Kingdom)》. They have made some progress in their research.Category: esters-buliding-blocks The article mentions the following:

A general method for the synthesis of structurally diverse N-arylpyrazoles I [R = H, 3-Me, 4-Cl, etc.; R1 = c-Pr, Ph, 3-thienyl, etc.; R2 = H, Me, Et, etc.] from readily available cyclopropanols and aryldiazonium salts was disclosed. The reaction was conducted at room temperature within minutes with a broad substrate scope and excellent regioselectivity. And Methyl 3-methylbenzoate (cas: 99-36-5) was used in the research process.
