119-39-1, 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. Phthalazin-1(2H)-one, cas is 119-39-1,the phthalazine compound, it is a common compound, a new synthetic route is introduced below.
A mixture of 4-(2-bromoethoxy)benzaldehyde (4.97g), 1(2H)-phthalazinone (3.27 g), potassium carbonate (6.20 g) and N,N-dimethylformamide (50 ml) was stirred at 80C for 5 hours. After cooling, the reaction mixture was poured into water, which was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium chloride solution, dried (MgSO4) and concentrated to obtain 4-[2-[1-oxo-2(1H)-phthalazinyl]ethoxy]benzaldehyde (5.36 g, yield 84%) as colorless crystals. This was recrystallized from ethyl acetate-hexane. Melting point: 126-127C
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of Phthalazin-1(2H)-one, 119-39-1
