59-49-4, 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. 2-Benzoxazolinone, cas is 59-49-4,the benzoxazole compound, it is a common compound, a new synthetic route is introduced below.
To a mixture of 3H-benzooxazol-2-one (20 g, 0.15 mol) in DCM (500 mL) was added bromine (8.34 mL, 0.16 mol). After stirring at room temperature for 19.5 h, the orange precipitate that had formed was filtered off and washed with DCM until the orange color was washed out. The filtrate was concentrated to approximately 33% of its original volume and filtered and washed as before. The combined solids weighed 28.36 g. 1H NMR indicated the product was clean albeit contained ca. 8-9% starting material meaning the true yield of product was 26.72 g, 84%.
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 2-Benzoxazolinone, 59-49-4
