Chen, Lu et al. published their research in Chinese Journal of Chemistry in 2019 | CAS: 85118-24-7

2-Bromo-4-(trifluoromethyl)benzaldehyde (cas: 85118-24-7) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.COA of Formula: C8H4BrF3O

Lewis Acid-Catalyzed Intramolecular [3+2] Cross-Cycloaddition of Donor-Acceptor Epoxides with Alkenes for Construction of Oxa-[n.2.1] Skeletons was written by Chen, Lu;Tian, Jun;Zhan, Yizhou;Ren, Jun;Wang, Zhong-Wen. And the article was included in Chinese Journal of Chemistry in 2019.COA of Formula: C8H4BrF3O This article mentions the following:

The first LA-catalyzed [3+2] intramol. cross-cycloaddition of GDA-epoxides with carbon-carbon double bonds was developed for construction of bridged oxa-[n.2.1] skeletons I [R1 = H, 7-F, 7-Me, etc.; R2 = R3 = Me, OMe]. In the experiment, the researchers used many compounds, for example, 2-Bromo-4-(trifluoromethyl)benzaldehyde (cas: 85118-24-7COA of Formula: C8H4BrF3O).
