In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Reaction of guanine with glycidol, published in 2009-02-28, which mentions a compound: 3066-84-0, Name is 8-Bromoguanine, Molecular C5H4BrN5O, Quality Control of 8-Bromoguanine.
Reaction of guanine with glycidol regiospecifically gave 2-amino-6-oxo-9-(2,3-dihydroxypropyl)purine. Reaction of 8-bromoguanine with glycidol gave a mixture of 2-amino-6-oxo-8-bromo-3- and 9-(2,3-dihydroxypropyl)purine.
Compound(3066-84-0)Quality Control of 8-Bromoguanine received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(8-Bromoguanine), if you are interested, you can check out my other related articles.
