Application of 271-70-5, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.271-70-5, name is 7H-Pyrrolo[2,3-d]pyrimidine, molecular formula is C6H5N3, molecular weight is 119.124, as common compound, the synthetic route is as follows.
5-Nitro-7H-pyrrolo[2,3-d]pyrimidine (8) is prepared by adding 7H-pyrrolo[2,3-d]pyrimidine (6) to fuming nitric acid while cooling (e.g. 0 C.). After stirring for one to several hours, water is carefully added and the mixture neutralized with saturated sodium bicarbonate. The solids are collected by filtration and dried to provide 5-nitro-7H-pyrrolo[2,3-d]pyrimidine 8.
The chemical industry reduces the impact on the environment during synthesis 271-70-5, I believe this compound will play a more active role in future production and life.
