What are the synthesis methods of 3-methyl-1,2-benzothiazole-1,1-dione?

To prepare 3-methyl-1,2-benzothiazole-1,1-dione, there are various methods. First, anthranilic acid can be used as the starting material. First, the anthranilic acid is reacted with dimethyl sulfate to make the amino methylation to obtain N-methyl anthranilic acid. This step requires temperature control and reaction time to prevent side reactions. After that, the N-methyl anthranilic acid is reacted with sulfuryl chloride to generate N-methyl-2-chlorobenzamide-6-sulfonic acid. Pay attention to the amount of sulfuryl chloride and reaction conditions during the reaction, and the yield. Then through the cyclization reaction, in a suitable alkali solution, such as sodium hydroxide solution, heat to promote its cyclization, to obtain 3-methyl-1,2-benzothiazole-1,1-dione.

Second, take 2-methylaniline as the starting material. First, through the sulfonation reaction, it is co-heated with concentrated sulfuric acid to obtain 2-methyl-5-aminobenzenesulfonic acid. This step pays attention to temperature control to avoid excessive sulfonation. Then it reacts with phosgene to form the corresponding isocyanate intermediate. The process needs to be operated under the protection of inert gas and temperature control. Then it reacts with hydrogen sulfide or sodium hydrosulfide to introduce sulfur atoms, and finally reacts with oxidation, such as hydrogen peroxide as an oxidizing agent, in a suitable solvent to obtain the target product.

Third, o-toluidine and carbon disulfide are used as raw materials. The two are first reacted under alkali catalysis, such as potassium carbonate, to form dithiocarbamate. After oxidation cyclization, oxidation with iodine or hydrogen peroxide, 3-methyl-1,2-benzothiazole-1,1-dione can be obtained. Each method has its advantages and disadvantages, and the actual operation needs to be selected according to the availability of raw materials, cost and product purity requirements.

How safe is 3-methyl-1,2-benzothiazole-1,1-dione?

3-Methyl-1,2-benzothiazole-1,1-dione, this substance is related to safety and needs to be examined in detail. Looking at its chemical structure, benzothiazole is linked to methyl and diketone groups, and the structure is unique or endows it with different properties, which are closely related to safety.

First, toxicity, after many studies, it is toxic under specific conditions or to organisms. In animal experiments, if a certain dose is ingested, or the biochemical indicators of the body are abnormal, such as organ function disturbance, affecting the normal metabolism of liver and kidney. For the human body, although there are relatively few studies on direct contact, but analogous compounds with similar structures, long-term exposure or contact through the respiratory tract and skin, have potential health risks, or irritate the skin, mucous membranes, and cause inflammation and other discomforts.

Again on stability, under normal temperature and pressure, the substance is relatively stable. In case of high temperature, open flame or strong oxidant, it may react violently. Because the molecule contains heteroatoms such as sulfur and oxygen, it can participate in chemical reactions or form new substances under specific conditions, and some or more dangerous, such as flammable and explosive.

Also referred to as environmental effects, if this substance is accidentally released into the environment, in soil and water, its structure is relatively complex, and it may take a long time to degrade.
