Therefore, (5E) -5 - [ (2-methoxy-5-methyl-4-thiophenyl) cyano] -6-oxo-5,6-dihydrothiophene-2-carboxylic acid cobalt salt is successfully prepared. The whole preparation process requires strict control of the reaction parameters of each step and fine operation to obtain a high-purity target product.

(5E) -5 - [ (2-amino-5-methyl-4-thiazolyl) pyridine] -6-oxo-5,6-dihydropyrimidine-2-carboxylate cobalt During use, there are many precautions as follows:
First, it is related to the operating environment. When using this substance, the operation needs to be carried out in a well-ventilated place. Because it may emit certain chemical gases, if the ventilation is poor, the gas accumulates, or it is unfavorable to human health, causing dizziness, nausea and other uncomfortable symptoms, it may also affect the reaction process.
Second, about personnel protection. Operators must wear appropriate protective equipment. Protective gloves should be worn to prevent skin contact, because it may irritate and corrode the skin, cause skin allergies, burns, etc.; protective glasses and masks should also be worn to avoid substances splashing into the eyes and prevent inhalation of its dust or volatile gases, causing damage to the eyes and respiratory tract.
Third, it involves storage conditions. It should be stored in a dry and cool place, away from fire and heat sources. Due to its chemical properties or instability, high temperature, humid environment or deterioration will affect the use effect. It is more likely to cause fire or even explosion if it is close to the fire source.
Fourth, it is related to the use specifications. Use in strict accordance with the prescribed dosage and operating procedures. Improper dosage, or reaction can not achieve the desired effect, or produce side reactions, generating other unnecessary substances; not operating according to the process, not only the experiment or production failure, but also may cause safety accidents.
Fifth, pay attention to waste disposal. After use, the remaining substances and waste cannot be discarded at will. It is necessary to properly dispose of in accordance with relevant environmental protection regulations to prevent pollution to the environment and endanger the ecological balance.
