To prepare (3R) -tetrahydrofuranamine 4-methylbenzenesulfonate, the method is as follows:
First prepare all kinds of raw materials, (3R) -tetrahydrofuranamine and 4-methylbenzenesulfonyl chloride are the key things, and also need suitable solvents, such as dichloromethane, etc., and prepare acid binding agents, such as triethylamine, to assist the reaction.
In a clean and dry reaction vessel, first fill an appropriate amount of dichloromethane as a solvent, then carefully add (3R) -tetrahydrofuranamine, stir well, so that it is fully dissolved. Under low temperature and continuous stirring, slowly drop the solution of 4-methylbenzenesulfonyl chloride. Be sure to pay attention to the speed of dropwise addition during this process to prevent the reaction from being too violent. At the same time, add the acid binding agent triethylamine one by one to neutralize the acid generated by the reaction, so that the reaction equilibrium moves in the direction of the product.
Add it dropwise, raise it to a suitable temperature, generally between room temperature and 40 degrees Celsius, and continue to stir to allow the reaction to proceed fully. During this period, the reaction process can be monitored by thin layer chromatography (TLC) and other methods until the raw material point almost disappears, indicating that the reaction is almost complete.
After the reaction is completed, pour the reaction solution into an appropriate amount of water to extract and separate. The organic phase was washed with dilute acid, dilute alkali and saturated salt water to remove impurities. Then dried with anhydrous sodium sulfate to remove moisture from the organic phase.
Then, the crude product was obtained by distillation under reduced pressure to remove the solvent. To obtain high-purity (3R) -tetrahydrofuranamine 4-methylbenzenesulfonate, the crude product can be refined by column chromatography or recrystallization. During column chromatography, an appropriate eluent is selected to separate the product according to the polarity of the product and the impurities; for recrystallization, a suitable solvent is selected to recrystallize and precipitate the product in the solution. After filtration and drying, a pure (3R) -tetrahydrofuranamine 4-methylbenzenesulfonate is obtained.

3-Furanamine, tetrahydro-, (3R) -, 4-methylbenzenesulfonate, this is a chemical substance. During storage, many matters need to be paid attention to.
First, its physical and chemical properties need to be checked. This substance may be sensitive to heat, light, and moisture. If exposed to hot topics, or cause decomposition, deterioration, or even dangerous reactions. Therefore, it should be stored in a cool place, away from heat sources, such as heaters, steam pipes, etc. When exposed to light or its properties change, it should be placed in a dark place, such as a brown bottle, hidden in a dark cabinet. And moisture or cause its hydrolysis and deliquescence, it needs to be stored in a dry place, and a desiccant can be built into the storage container to keep the environment dry.
Second, related to the storage container. Suitable materials should be selected. Because the substance contains specific chemical groups, or reacts with certain materials. It is appropriate to use chemically stable containers, such as glass and specific plastics. Glass containers have good chemical stability and are not easy to react with substances. When choosing a plastic container, make sure it is not compatible with the substance. The container must be well sealed to prevent air and moisture from entering.
Furthermore, regarding the storage place. Should be kept away from fire sources and oxidants. Because of its flammability, contact with oxidants or cause violent reactions. And the field needs to be well ventilated. If the substance evaporates, it can be discharged in time to reduce the concentration in the air and reduce the danger.
In addition, the identification is crucial. The storage container must be clearly marked with the name, nature, hazard and other information of the substance. Even if times change, others can know its characteristics with the identification and take appropriate protection.
In the last case, regular inspection is also indispensable. Observe whether its appearance changes, such as discoloration and precipitation. Detect its properties. If there is any deterioration, deal with it quickly to ensure its quality and safety.

There is a question today as to whether 3-furanamine, tetrahydro-, (3R) -, 4-methylbenzene sulfonate is toxic.
To know the toxicity of this substance, it is necessary to investigate its chemical properties, related studies and past cases in detail. However, just looking at its name, it is difficult for us to make a hasty conclusion.
In the ancient book "Tiangong Kaiwu", although many process products are detailed, the modern chemical name of this substance is not included in the book, nor is there any relevant toxicity statement. Gai "Tiangong Kaiwu" was formed in the past, when the chemical understanding was very different from today, and the naming system was not used in modern chemistry.
Under the current scientific understanding, many factors need to be considered to judge the toxicity of chemical substances. First, its molecular structure may contain specific functional groups, and some functional groups are often associated with toxicity in past studies. Second, past experimental studies on this substance or similar structures, if there are animal experiments, human exposure studies, etc., can reveal its impact on organisms. Third, the behavior of this substance in the environment, such as degradability and bioaccumulation, is also related to toxicity. If it is difficult to degrade and easily accumulates in organisms, it may be potentially harmful.
However, based on the available information, it is difficult to know for sure whether 3-furanamine, tetrahydro-, (3R) -, 4-methylbenzene sulfonate is toxic. To be sure, it is necessary to further consult modern chemical research materials, professional databases, or consult experts in the field of chemistry.
