Reactivity of thienopyrroles. Synthesis of isomeric nitro and bromothienopyrroles was written by Eras, J.;Galvez, C.;Garcia, F.. And the article was included in Journal of Heterocyclic Chemistry in 1984.HPLC of Formula: 18791-79-2 This article mentions the following:
The isomeric thienopyrroles I and II (R = H, Br) were prepared by thermal cyclization of the azidothienylacrylates III and IV. III and IV were prepared from the corresponding thiophenecarboxaldehydes and N3CH2CO2Et. I and II (R = NO2) were prepared by nitration of I and II (R = H). In the experiment, the researchers used many compounds, for example, 5-Bromothiophene-3-carbaldehyde (cas: 18791-79-2HPLC of Formula: 18791-79-2).
5-Bromothiophene-3-carbaldehyde (cas: 18791-79-2) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). 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.HPLC of Formula: 18791-79-2
