Besides solubility, its performance varies in organic solvents. In common alcoholic solvents such as methanol and ethanol, it has a certain solubility, just like a fish entering water. Although it cannot be completely dissipated and invisible, it can be fused with the solvent to form a uniform system. In water, the solubility is very small, just like oil floating in water, it is difficult to fuse. This characteristic comes from the role of hydrophobic groups in its molecular structure.
When it comes to the melting point, it is about 150-155 ° C. When the temperature gradually rises near the melting point, the compound is awakened like a sleeping spirit, and begins to transform from a solid state to a liquid state. The lattice structure gradually disintegrates, and the intermolecular forces are readjusted until it is completely transformed into a flowing liquid, like ice and snow melting and gurgling.
In terms of boiling point, under certain pressure conditions, its boiling point is higher, and it needs to reach a specific high temperature in order to convert it from liquid to gaseous state, break free from the shackles of the liquid phase, and soar in the gas phase. This characteristic makes its stability in high temperature environments much concerned.
Density is also its important physical property, about 1.3 - 1.4 g/cm ³, which is similar to the density of common organic compounds. This value reflects its mass per unit volume, just like the scale for measuring the "weight" of substances, which determines its floating performance in different media.

To prepare (7aR) -8,8-dimethylhexahydro-3a, 6-methylene-2,1-benzothiazole 2,2-dioxide, there are many methods, each with its own advantages.
First, you can start from the corresponding thiazoline precursor. First, replace thiophenol and alkenyl-containing halogenates with suitable substitutions, and under the catalysis of bases, through nucleophilic substitution reaction, form thioenyl-containing intermediates. In this step, mild reaction conditions need to be selected, and the reaction temperature and time should be controlled to avoid side reactions. Then, the intermediate is reacted with a suitable dienolefin, Diels-Alder, to form a six-membered cyclic structure. This reaction requires strict spatial configuration of the reactants, and precise control of the ratio of the reactants and the reaction environment is required. Finally, through the oxidation step, the sulfur atom is oxidized to dioxide with an appropriate oxidant, such as m-chloroperoxybenzoic acid, etc., to obtain the target product.
Second, benzothiazole can also be used as the starting material. First, the specific position of benzothiazole is alkylated, and the desired methyl group is introduced. This process requires the selection of suitable alkylation reagents and catalysts to ensure the accuracy of the alkylation check point. Next, by hydrogenation, some unsaturated bonds of benzothiazole are hydrosaturated to form a hexahydro structure. In this step, suitable metal catalysts, such as palladium carbon, can be selected, and the hydrogen pressure and reaction temperature can be adjusted. Finally, the same oxidation process is used to realize the oxidation of sulfur atoms to obtain (7aR) -8,8-dimethylhexahydro-3a, 6-methylene-2,1-benzothiazole 2,2-dioxide. The method of
preparation requires considering the availability of raw materials, the difficulty of reaction, the level of cost and the advantages and disadvantages of yield according to the actual situation, making careful choices and fine operation to achieve the best situation.

(7aR) -8,8-dimethylhexahydro-3a, 6-methylene-2,1-benzothiazole 2,2-dioxide This product, when used, there are several ends to be aware of.
First, safety is the first thing to pay attention to. This compound may have specific chemical activity and latent risk.
