6-Chloro-1H-benzimidazole can be synthesized in various ways. The first method is to use o-phenylenediamine and ethyl chloroformate as the starting material, and control the temperature in an appropriate solvent to make the reaction. First, the o-phenylenediamine is mixed with ethyl chloroformate. The solvent such as ethanol has a moderate temperature, which is common in a water bath, so that it slowly synthesizes. After the reaction is completed, the separation technique is applied. After distillation and extraction, the primary product is obtained, and then the essence is recrystallized to obtain pure 6-chloro-1H-benzimidazole.
Another method starts with o-nitroaniline. After the reduction of o-nitroaniline, o-phenylenediamine is obtained. The reducing agent used, such as the combination of iron filings and hydrochloric acid, or hydrogen plus a suitable catalyst. When o-phenylenediamine is obtained, it is reacted with chloroacetic acid in an alkaline environment. Alkali such as sodium hydroxide, adjust its pH, control its reaction conditions, and combine the two. Afterwards, through the steps of acidification, separation, and purification, the target product can also be obtained. When acidifying, its acidity should be carefully controlled to prevent damage to the product. When separating, filtration or liquid separation methods may be used, depending on the characteristics of the product. Purification depends on recrystallization, and a suitable solvent is selected to precipitate the product into pure crystals.
In addition, o-phenylenediamine and trichloroacetyl chloride are used as raw materials to react in an organic solvent such as dichloromethane in the presence of an acid binding agent such as triethylamine. The amount of acid binding agent needs to be considered appropriately. If it is too little, the reaction will not be enough. If it is too much, it will increase the cost and lead to impurities. After the reaction is completed, it is washed with water, dried, and column chromatography to obtain pure 6-chloro-1H-benzimidazole. Washing with water is designed to remove impurities, and drying is to remove water. Column chromatography is a good method for further purification. According to the difference between the product and the impurities in the fixed phase and the mobile phase, the two are separated.

6-Chloro-1H-benzimidazole is an organic compound. During storage and transportation, the following matters must be paid attention to:
One is the storage environment. A cool, dry and well-ventilated place should be selected. This is because if the compound is in a humid environment, it may be deteriorated by moisture, which will affect its quality and performance. If it is stored in a humid place in the south, it is easy to cause it to absorb moisture and agglomerate. And the temperature must also be controlled. Excessive temperature may cause its chemical changes, or even cause danger. If the warehouse temperature is too high, or the stability of the compound may be affected. Therefore, it is necessary to avoid fire and heat sources, and the warehouse temperature should be maintained within a suitable range.
The second is related to packaging. The packaging must be tight to ensure a good seal. This can prevent it from contacting with air, moisture, etc., and avoid reactions such as oxidation and hydrolysis. It is commonly packaged in sealed bags or sealed drums. The packaging materials are also exquisite. It must be resistant to chemical corrosion and do not react with 6-chloro-1H-benzimidazole to avoid leakage due to package damage.
The third is transportation safety. During transportation, it is necessary to prevent collision, vibration and friction. The compound leaks due to violent collision or vibration, or the package is damaged. And it should be transported separately from oxidants, acids, bases, etc. Because 6-chloro-1H-benzimidazole or chemical reactions with these substances cause danger. If mixed with strong oxidizing agents, or a violent oxidation reaction, it can cause fire or even explosion.
Fourth, the label is clear. Storage places and transportation vehicles should be clearly marked, indicating "6-chloro-1H-benzimidazole" and its dangerous characteristics and other information. In this way, the staff can see at a glance, and the operation and emergency response can be properly handled according to the label information to avoid operation errors due to unknown circumstances and cause safety accidents.
