The synthesis method of 5-methyl-2-mercapto-1H-benzimidazole, although the ancient book "Tiangong Kaiwu" does not specify the synthesis of this specific compound, it contains chemical process wisdom, or a similar synthesis idea can be inferred.
In the past, the preparation of such nitrogen-containing heterocyclic compounds with mercapto groups often began with the corresponding o-phenylenediamine and reagents containing sulfur and methyl. You can first take o-phenylenediamine, with methyl-containing carboxylic acids or their derivatives, in a suitable reaction environment, such as using an appropriate acid as a catalyst, heating to promote its condensation, to form 5-methylbenzimidazole intermediates. This step requires temperature control and time control to prevent side reactions. The thiol group is then introduced. The common method is to react with the above intermediates with sulfur-containing reagents such as sodium hydride or thiourea. If sodium hydride is used, in an alkaline environment, its thiohydrogen ion attacks the intermediate nucleophilically and replaces the suitable group, then 5-methyl-2-mercapto-1H-benzimidazole is obtained. After the reaction, it needs to be separated and purified, such as recrystallization, column chromatography, etc., to obtain a pure product.
Although "Tiangong Kaiwu" does not have this precise synthesis, its principles of material transformation and process regulation can open up ideas for the synthesis of this compound today, and can be used for reference in the exploration of reaction conditions and the selection of reagents.

5-Methyl-2-mercapto-1H-benzimidazole, when storing and transporting, pay attention to many matters.
The first to bear the brunt, this substance is extremely sensitive to temperature and humidity. It should be stored in a cool, dry place to prevent its properties from changing due to excessive temperature and humidity. If placed in a hot flush place, it may cause chemical reactions and damage the quality.
In addition, it has a certain chemical activity and must be stored in isolation from oxidants, acids, etc. Contact with these substances can easily cause violent reactions, or cause the risk of combustion and explosion. As the ancients said: "Water and fire are incompatible", there is also such resistance between chemical substances.
When transporting, the packaging must be tight and stable. To prevent bumps and collisions on the way, causing damage to the packaging and leakage of the substance. Leakage not only damages the environment, but also poses a threat to human health. Because of its irritation and toxicity, accidental contact with the skin or inhalation into the body can cause physical discomfort.
It should also be noted that the storage place should be well ventilated. If the ventilation is not smooth, the volatile gas will accumulate and reach a certain concentration. In case of open fire or static electricity, there is a risk of explosion. Transportation vehicles should also be equipped with corresponding fire and leakage emergency treatment equipment for emergencies.
When storing and transporting 5-methyl-2-mercapto-1H-benzimidazole, be careful, follow relevant regulations, and do not take it lightly to ensure safety.

The effects of 5-methyl-2-mercapto-1H-benzimidazole on the environment and human health are discussed in detail.
At the environmental end, if 5-methyl-2-mercapto-1H-benzimidazole flows into natural water bodies, it may cause water pollution. Its chemical properties may interfere with the normal physiological metabolism of aquatic organisms, causing their growth and reproduction to be hindered. In the soil, or change the chemical properties of the soil, affect the soil microbial community, and then affect the absorption of nutrients by plant roots, damaging vegetation growth. If it evaporates into the atmosphere, or participates in photochemical reactions, it affects the quality of the atmosphere, or even forms secondary pollutants, endangering the surrounding ecological environment.
As for human health, this substance may have adverse effects on many systems of the human body after entering the body through respiratory tract, skin contact or accidental ingestion. First, it may irritate the respiratory mucosa, causing symptoms such as cough and asthma, and long-term exposure may cause chronic respiratory diseases. Second, contact with the skin, or cause allergic reactions, such as skin itching, redness, swelling, and rash. Third, after ingestion through the digestive system, it may damage the gastrointestinal mucosa, causing nausea, vomiting, abdominal pain and other discomfort. And this substance accumulates in the body for a long time, or affects the human endocrine system, interferes with hormone balance, and may also cause potential harm to reproductive, immune and other systems. Therefore, the use and discharge of 5-methyl-2-mercapto-1H-benzimidazole should be handled with caution to prevent it from causing serious harm to the environment and human health.
