The synthesis method of 2-amino-5,6-dichlorobenzimidazole is important in the field of chemical preparation. There are many methods, so choose to describe them.
One is to use o-phenylenediamine and dichloroacetic acid as raw materials. The two are heated in a suitable reaction vessel and in the presence of an acid catalyst to undergo a condensation cyclization reaction. In this process, the amino group of o-phenylenediamine interacts with the carboxyl group of dichloroacetic acid to gradually form a ring. After carefully controlling the reaction temperature, time and raw material ratio, the target product can be obtained. For example, the reaction temperature may be controlled at 120-150 ° C, and the reaction time is several hours. The conditions are fine-tuned according to the purity of the raw materials and the reaction equipment to achieve higher yields.
Second, take 2-nitro-5,6-dichloroaniline as the starting material. First reduce it to 2-amino-5,6-dichloroaniline, commonly used reducing agents such as iron powder, zinc powder or lithium aluminum hydride. After obtaining 2-amino-5,6-dichloroaniline, it is cyclized with reagents such as formic acid or formamide under heating conditions to generate 2-amino-5,6-dichlorobenzimidazole. In this path, the reduction step needs to pay attention to the reaction conditions to prevent excessive reduction; the cyclization step also needs to control the temperature and reaction process to make the reaction proceed smoothly.
Third, 5,6-dichlorobenzimidazole-2-one is used as raw material. Under the action of appropriate amination reagents, such as ammonia, amine compounds, etc., amination reaction occurs under high temperature and high pressure conditions, and the carbonyl group is converted into an amino group to obtain 2-amino-5,6-dichlorobenzimidazole. This process requires high reaction equipment, which needs to be able to withstand high temperature and pressure, and the reaction parameters must be strictly controlled to ensure the quality and yield of the product.
All synthesis methods have advantages and disadvantages. Raw material cost, reaction conditions, product purity and yield all need to be weighed before the optimal method can be selected to obtain 2-amino-5,6-dichlorobenzimidazole efficiently in actual production or research.

It is difficult to determine the price range of 2-amino-5,6-dichlorobenzimidazole in the market. The price often varies due to many factors, such as the quality, the situation of supply and demand, the distance of origin, the batch size of the transaction, and the fluctuation of the market.
Looking at the examples of past transactions, the price of high quality and large quantities may be relatively low. If the quality is excellent, the supply is abundant, and there are few buyers, the price will tend to drop; conversely, if the quality is slightly inferior, the demand will be strong, the supply will be in short supply, and the price will rise easily. Different origins have different costs. For those who are shipped from afar, the price may be higher due to freight, etc.
To know the exact price range, you need to pay attention to the current market conditions. You can consult the chemical raw material suppliers, and many merchants' quotations can be cross-referenced to obtain a more accurate range. Or refer to the recent transaction price of the chemical product trading platform, which is also the way to know the price. However, this equivalent price is not static, and you must always pay attention to market dynamics in order to grasp the trend of its price.
