Zhu, Zhaofu et al. published their research in Huaxue Yanjiu Yu Yingyong in 2003 | CAS: 28657-75-2

1-(6-Aminobenzo[d][1,3]dioxol-5-yl)ethanone (cas: 28657-75-2) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Dioxole functionalized metal-organic frameworks have also been recently reported.COA of Formula: C9H9NO3

Synthesis and characterization of 4-substituted ethyl 2-methyl-6,7-methylenedioxy-3-quinolinecarboxylate was written by Zhu, Zhaofu. And the article was included in Huaxue Yanjiu Yu Yingyong in 2003.COA of Formula: C9H9NO3 This article mentions the following:

Et 4-R-2-methyl-6,7-methylenedioxy-3-quinolinecarboxylate (R = Me, Et, Pr, or isopropyl) was prepared from benzodioxole by acylation, nitration, reduction, and condensation in a yield of 74-87%. The mol. structures were determined by IR, 1H-NMR, and MS. In the experiment, the researchers used many compounds, for example, 1-(6-Aminobenzo[d][1,3]dioxol-5-yl)ethanone (cas: 28657-75-2COA of Formula: C9H9NO3).
