The synthesis of 2-thiophenoformyl hydrazide requires a multi-step reaction process. First, 2-thiophenoformyl acid is used as the starting material, and it is co-placed with thionyl chloride in a suitable reaction vessel, accompanied by an appropriate amount of catalyst, often pyridine as the catalyst. Heating causes the two to undergo an acyl chloride reaction. During this process, the carboxyl group of 2-thiophenoformyl acid is converted into an acyl chloride group to generate 2-thiophenoformyl chloride. The reaction formula is roughly as follows: 2-thiophenoformyl acid + thionyl chloride → 2-thiophenoformyl chloride + sulfur dioxide + hydrogen chloride.
Next, the obtained 2-thiophenoformyl chloride is slowly dropped into the alcohol solution containing hydrazine, which is mostly hydrazine hydrate. This step is carried out under low temperature and stirring conditions, aiming to make 2-thiophenoformyl chloride and hydrazine undergo nucleophilic substitution reaction, and the acid chloride is replaced by hydrazine to generate 2-thiophenoformyl hydrazide. The specific reaction formula is: 2-thiophenoformyl chloride + hydrazine → 2-thiophenoformyl hydrazide + hydrogen chloride.
After the reaction is completed, the reaction mixture is properly treated. The solvent is usually removed by vacuum distillation, and then the product is purified by recrystallization. Select a suitable solvent, such as ethanol, ethyl acetate, etc., dissolve the product in a hot solvent, and then slowly cool down to allow 2-thiophenylhydrazide to crystallize and precipitate. After suction filtration, drying and other steps, a pure 2-thiophenylhydrazide product can be obtained. This synthesis method requires attention to the precise control of the reaction conditions, such as temperature, proportion of reactants, reaction time, etc., which are all related to the yield and purity of the product. When operating, be careful.

2-Thiophenylhydrazide is a chemical substance. During storage and transportation, there are a number of things to pay attention to and should not be ignored.
First words storage, this substance should be placed in a cool, dry and well-ventilated place. Because of its nature or fear of heat and moisture, if it is in a high temperature or humid place, it may cause changes in its properties or biochemical reactions, which will damage its quality. And keep away from fires, heat sources, and chemical substances. They are more flammable and easy to fry. If you are not careful, you will cause a disaster. In addition, they should be stored separately from oxidizing agents, acids, and bases. Mixing different chemicals can easily cause violent reactions and endanger safety. Storage places also need to be prepared with suitable materials to contain leaks, just in case.
As for transportation, it is necessary to ensure that the packaging is complete and the loading is safe. During transportation, the speed of the vehicle should be stable, and it should not be braked or turned abruptly to prevent package damage. Transportation vehicles should also travel according to the specified route, and do not approach densely populated places to avoid risks. At the same time, transportation personnel need to be professionally trained to be familiar with the characteristics of the substance and emergency treatment methods. If there is a leak on the way, it can be properly disposed of in time to avoid major disasters. All of these are the things that should be paid attention to when storing and transporting 2-thiophenylhydrazide, and must be kept in mind to ensure safety.

2-Thiophenyl hydrazide, the price of this product in the market is difficult to determine quickly. The change in its price depends on many reasons.
First of all, the trend of supply and demand is essential. If there are many people in the market who want it, it is used in the pharmaceutical, chemical synthesis and other industries. The demand is very large, but the production is few, and the goods are rare and difficult to find, the price will rise. On the contrary, if the supply exceeds the demand, the goods will be stored in the market, and there will be no more customers to ask, and the price will drop.
Both, the price of raw materials will also affect the price. 2-Thiophenyl hydrazide The system depends on various raw materials, and the rise and fall of raw material prices is directly related to its cost. If the price of raw materials rises, the manufacturer must raise the price of 2-thiophenylhydrazide in order to protect its profits; if the price of raw materials falls, the price may also be reduced accordingly.
Of the three, the difficulty of the process is related to the cost. If the process is difficult, requires fine tools and materials, and consumes a lot of manpower and material resources, the cost is high and the price is not cheap. If the process is simple and cost-effective, the price may be close to the people.
Furthermore, the state of market competition also has an impact. If there are many businesses competing with each other to attract customers and compete for profits, or there may be price reductions. However, if the market has few competitors and is almost monopolized, the price can be autonomous and often remains high.
And the price varies depending on the region. In places with abundant materials and convenient transportation, the cost may be low and the price may be slightly reduced; in remote places with scarcity, transportation and other expenses may be imposed on it, and the price may be higher.
In summary, the market price of 2-thiophenylhydrazide is volatile and varies according to the above factors. To know its exact price, it is necessary to carefully observe the current market situation.
