The method of preparing 3-chloro-5- (trifluoromethyl) pyridine-2-carbothiamide depends on the technique of chemical synthesis. The way may have the following ends.
First, it can be started by a compound containing the corresponding pyridine structure. Take 3-chloro-5- (trifluoromethyl) pyridine-2-carboxylic acid as raw material and let it react with carbon disulfide and ammonia under appropriate conditions. Among them, carbon disulfide is used as a vulcanization reagent, and ammonia water is used as an amino group. The two interact with pyridinecarboxylic acid and go through specific reaction steps, or can generate the target 3-chloro-5- (trifluoromethyl) pyridine-2-carbothiamide. When reacting, pay attention to the temperature, reaction time and proportion of reactants. If the temperature is too high or side reactions are clustered, if it is too low, the reaction will be delayed, and the proportion will not be ideal.
Second, 3-chloro-5- (trifluoromethyl) pyridine-2-formonitrile is used as the starting material. Co-place it with hydrogen sulfide and a suitable catalyst in a suitable reaction system. The sulfur atom of hydrogen sulfide and the formonitrile group are catalyzed and gradually converted into a thiamide structure. In this process, the choice of catalyst is very critical, and the activity and selectivity of different catalysts are different, which may affect the reaction rate and product purity. At the same time, the pH, temperature and other conditions of the reaction system also need to be carefully controlled to ensure the smooth progress of the reaction and improve the yield of the product.
Third, if 3-chloro-5- (trifluoromethyl) pyridine-2-halogen is used as a raw material, it can react with reagents containing sulfur and amino groups, such as thioacetamide. The halogen atom of the halogenated compound has high activity, and can undergo substitution reaction with the sulfur atom and amino group of thioacetamide to gradually construct the carbon-sulfur amide structure of the target molecule. However, in this process, substitution reactions at other positions need to be prevented, and the selectivity of the reaction can be improved by means of steric hindrance effect or protective group.
In short, the synthesis of 3-chloro-5- (trifluoromethyl) pyridine-2-carbothiamide has its own advantages and disadvantages. In actual operation, it is necessary to comprehensively weigh factors such as raw material availability, cost, yield and purity requirements to choose the best path.

3-Chloro-5- (trifluoromethyl) pyridine-2-carbothiamide is also a chemical substance. When storing and transporting, many things need to be paid attention to.
First words storage. This substance should be stored in a cool, dry and well-ventilated place. Because of the cool environment, it can reduce the risk of chemical reactions caused by excessive temperature. If it is exposed to high temperature, or causes decomposition and deterioration, it will damage its chemical properties and quality. Dry places are also critical because they are afraid of moisture, contact with water or water vapor, or react with hydrolysis, causing changes in composition. Good ventilation can prevent the accumulation of harmful gases and ensure the safety of the storage environment.
Furthermore, when storing, it should be stored separately from oxidizing agents, acids, alkalis, etc. This is because the chemical properties of the substance are active, and contact with the above-mentioned substances is prone to violent chemical reactions, or serious consequences such as combustion and explosion.
As for transportation, it is necessary to ensure that the packaging is complete and sealed. To prevent material leakage during transportation, pollute the environment, and endanger the safety of transporters and surrounding people. The selected means of transportation also need to be adapted, and should have functions such as anti-leakage, fire protection, and explosion-proof. During transportation, bumps, vibrations, and impacts should be avoided to avoid package damage, and temperature control should be strictly maintained to maintain a suitable ambient temperature.
In addition, whether it is storage or transportation, professional supervision is required. They should be familiar with the characteristics of the substance and emergency treatment methods. In case of emergencies, such as leakage, fire, etc., they can respond in a timely and appropriate manner to minimize the harm.
