188614-01-9, 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. Methyl 3-oxo-3,4-dihydro-2H-1,4-benzothiazine-6-carboxylate, cas is 188614-01-9,the thiazines compound, it is a common compound, a new synthetic route is introduced below.
3-QxQ-3, 4-dihydro-2H-benzo [1, 48thiazine-6-carboxylic acid methyl ester (6.74g) was suspended in tetrahydrofuran (lOOmL) and 2M sodium hydroxide (30mL) was added followed by water (20mL). The solution was stirred for 2.5 hours, evaporated to half volume and acidified with 2M hydrochloric acid. The product was collected, washed with water and dried in vacuo, to give a white solid (6.2g). MS (-ve ion electrospray) m/z 208 (M-H)-
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 188614-01-9, Methyl 3-oxo-3,4-dihydro-2H-1,4-benzothiazine-6-carboxylate
