The physical properties of 2-mercapto-5-methoxy-1H-benzimidazole are as follows:
This substance is mostly solid at room temperature. Looking at its appearance, it is usually white to light yellow powder with fine texture and smooth touch. Its melting point is quite critical, about 170-175 ° C. At this temperature, it gradually melts from solid to liquid, just like ice and snow melting in spring.
As for solubility, it is quite difficult to dissolve in water, just like a stubborn stone entering water, and it is difficult to melt with water. However, in organic solvents, it has different performances. In common organic solvents such as methanol and ethanol, it has a certain solubility, just like a fish getting water, and can be dispersed in it. In dichloromethane, the dissolution state is better, and it can be evenly dispersed to form a uniform system.
The density of this substance is about 1.3-1.4 g/cm ³, which is heavier than water. If placed in water, it will be like a stone sinking to the bottom of the water. Its stability is also considerable. Under general environmental conditions, it can maintain its own structure and properties for a long time, just like a stable old man, and it is not easily moved by the outside world. When encountering strong acids and alkalis, its structure may change, and its properties will also change accordingly. Just like a delicate flower encountering wind and rain, it will inevitably be damaged. The smell is weak, close to sniff, and there is a faint special breath, which is indescribable, but unique.

The chemical synthesis method of 2-mercapto-5-methoxy-1H-benzimidazole is detailed as follows.
To obtain this compound, the common starting materials are 4-methoxy-1,2-phenylenediamine and ammonium thiocyanate. First take an appropriate amount of 4-methoxy-1,2-phenylenediamine and put it in a clean reaction vessel. Then slowly add ammonium thiocyanate in a certain proportion. The ratio of the two needs to be accurate, which is one of the keys to the synthesis.
Subsequently, add an appropriate amount of organic solvent, such as ethanol, to the container. Its function is to promote the uniform dispersion of the raw materials, which is conducive to the full progress of the reaction. After stirring, the temperature of the reaction system is gradually raised to a specific range, generally between about 80 and 100 degrees Celsius. Maintain this temperature and continue to stir, and the reaction lasts for several hours, during which the reaction process is closely observed.
When the reaction reaches the desired level, cool the reaction mixture. After that, use suitable separation methods, such as filtration and extraction, to obtain a mixture containing the target product. Then, by recrystallization, the product is further purified. Select a suitable solvent, such as a mixed solvent of methanol, ethanol and water, heat and dissolve the mixture containing the product, and then slowly cool to allow the target product to precipitate in crystal form. Finally, the crystals were filtered and dried to obtain pure 2-mercapto-5-methoxy-1H-benzimidazole. During the whole synthesis process, the ratio of raw materials, reaction temperature, time control and purification steps are all crucial, and fine operation is required to obtain the product with ideal yield and purity.

The price range of 2-mercapto-5-methoxy-1H-benzimidazole in the market is difficult to determine. The price often changes due to many reasons, such as the quality of the quality, the state of supply and demand, the cost of the system and the competition in the market.
Looking at the past, if the quality is high, the supply is less than the demand, and the price may increase; if the quality is flat, the supply exceeds the demand, and the price may drop. And this chemical is used in various industries, such as medicine, agriculture, chemicals, etc. Different industry needs also affect its price.
In the chemical raw material market, the price per kilogram of high quality may be in the hundreds of yuan. If it is industrial grade, when the quantity is large, the price per kilogram may drop to about 100 yuan. For those with high purity in the laboratory, the price is higher, or up to several thousand yuan per kilogram.
However, the market is volatile, and the price can change at any time. If a buyer wants to know the exact price, he should consult the supplier, compare its quotation, or observe the recent market situation report, and get a more accurate price.

2-Mercapto-5-methoxy-1H-benzimidazole is a very important chemical substance. When using, many things need to be paid attention to.
First, it is related to safety. This substance has certain chemical activity or is harmful to the human body. When operating, be sure to wear appropriate protective equipment, such as gloves, goggles, etc., to prevent it from coming into contact with the skin and eyes. If you accidentally touch it, rinse it with plenty of water immediately and seek medical attention according to the actual situation.
Second, about storage. Store it in a dry, cool and well-ventilated place, away from fire and oxidants. Due to its chemical properties, exposure to heat, oxidants, or the risk of reaction can cause it to deteriorate, or cause safety accidents.
Third, during use, precise control of the dosage is crucial. According to the specific experimental purpose or production needs, strictly follow the established formula and operating procedures. Too much or too little dosage may affect the final result.
Fourth, the environmental impact cannot be ignored. After use, the remaining materials and waste should be properly disposed of in accordance with relevant regulations, and must not be discarded at will to avoid polluting the environment.
Furthermore, when using this substance, relevant operators need professional training to be familiar with its characteristics, usage methods and emergency treatment measures. In this way, we can ensure the safety and efficiency of the use process, and give full play to its due effectiveness without any worries.
