In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 18740-38-0, name is Thieno[2,3-d]pyrimidine-2,4(1H,3H)-dione, the common compound, a new synthetic route is introduced below. Product Details of 18740-38-0
Thieno [2,3- D] pyrimidine-2,4 (1H, 3H) -dione (0.5 g, 2.98 mmol) HMDS (1.2 g, 7.44 mmol), toluene (8 mL) was added to the reaction flask, concentrated sulfuric acid (20 mg) was added with stirring, Stirring and refluxing reaction 12h. The solvent was concentrated to dryness under reduced pressure.
The synthetic route of 18740-38-0 has been constantly updated, and we look forward to future research findings.
