2-Amino-8-bromo-9-((2R,4S,5R)-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-1H-purin-6(9H)-one (cas: 13389-03-2) belongs to tetrahydrofuran derivatives. Tetrahydrofuran (THF) is a Lewis base that bonds to a variety of Lewis acids such as I2, phenols, triethylaluminum and bis(hexafluoroacetylacetonato)copper(II). Tetrahydrofuran can also be produced, or synthesised, via catalytic hydrogenation of furan. This process involves converting certain sugars into THF by digesting to furfural. An alternative to this method is the catalytic hydrogenation of furan with a nickel catalyst.Safety of 2-Amino-8-bromo-9-((2R,4S,5R)-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-1H-purin-6(9H)-one

A new method of synthesis of fluorescently labeled oligonucleotides and their application in DNA sequencing was written by Markiewicz, Wojciech T.;Groger, Gabriele;Rosch, Rudi;Zebrowska, Anna;Markiewicz, Maria;Klotz, Margit;Hinz, Michael;Godzina, Przemyslaw;Seliger, Hartmut. And the article was included in Nucleic Acids Research in 1997.Safety of 2-Amino-8-bromo-9-((2R,4S,5R)-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-1H-purin-6(9H)-one This article mentions the following:

A new approach to the chem. synthesis of oligodeoxynucleotides bearing reporter functional groups at base residues of 3′-end nucleosides is reported. Applications of the 3′-end fluorescently labeled primers for automated DNA sequencing are shown. In the experiment, the researchers used many compounds, for example, 2-Amino-8-bromo-9-((2R,4S,5R)-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-1H-purin-6(9H)-one (cas: 13389-03-2Safety of 2-Amino-8-bromo-9-((2R,4S,5R)-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-1H-purin-6(9H)-one).
