Ancient cocatalyst, or some plant ash or natural salts. Under suitable conditions, the intermediate gradually reacts with the raw material for constructing the thiazole ring to form 4- (4-pyridyl) thiazole-2-thiol.

The reaction is over, and the product may be mixed with impurities. At this time, separation and purification are required. Ancient separation method, or filtration, using fabric or fine sand and gravel as filter material to remove insoluble impurities. The pure 4- (4-pyridyl) thiazole-2-thiol was obtained by distillation according to the difference of boiling point of different substances. Although the ancient synthesis method is difficult to compare with the accuracy and efficiency of today, the wisdom of the ancients also laid the foundation for the development of chemistry and provided ideas for later synthesis research.

4- (4-pyridinyl) thiazole-2-thiol; 2-mercapto-4- (pyridine-4-yl) tniazole What are the precautions in storage and transportation?

4 - (4-pyridyl) thiazole-2-mercaptan; 2-mercapto-4 - (pyridyl-4-yl) thiazole. When storing and transporting this substance, there are a number of urgent precautions that need to be taken into account.

One is related to storage. Because of its nature or activity, it is advisable to find a cool, dry and well-ventilated storage. If placed in a warm and humid place, it may cause changes in its properties or biochemical reactions. For example, if the humidity is too high, water vapor or interaction with the substance will damage its purity and quality. Furthermore, it must be separated from oxidizing agents, acids, bases, etc. This is because the compound structure contains a thiol group, which has a certain degree of reduction and is easy to react with oxidants; while the pyridyl group makes the molecule alkaline to a certain extent, and the original material will be lost or deteriorated in case of acid or neutralization.

Second, about transportation. The packaging must be tight and stable. The material may be sensitive to vibration and collision. If the packaging is not good, bumps, impacts, or container ruptures during transportation, material leakage. And the transportation vehicle should be kept clean and free of other residual chemicals to prevent cross-contamination. Transportation personnel should also be familiar with the characteristics of this object. In the event of an accident such as a leak, they can quickly take appropriate measures according to their nature, such as evacuating the crowd, isolating the scene, and using appropriate materials for adsorption and cleaning, etc., to ensure the safety of the entire transportation process.
