Its nature is changeable, lively and agile. At room temperature, it is often in a gaseous state, free and unrestrained, like an uninhibited spirit, not constrained by square corners. When it is cold, it condenses, turning into droplets, like pearls and jade falling, lying quietly on the utensils, showing a warm and soft state. If it is very cold, it condenses into ice again, hard and clear, with the shape of a crystal, with a smooth edge, and a chill. Under this state, it is tough and brittle, and there is a risk of cracking when it touches a force.
Its chemistry is lively and can combine with many substances. When it comes to sodium, the reaction is violent.

To prepare and synthesize (6E) -6-imino-5- [2 - (4-cyano-2-thiazolylphenyl) ethyl] -4-oxo-4,6-dihydropyrimidine-2-carboxylic acid cobalt dicobalt, the method is as follows:
Prepare the required drugs first, and the drugs must be pure and accurate. In a clean vessel, add an appropriate amount of benzene derivatives containing cyanyl and thiazolyl. This is the base material for the initiation of the reaction. The quality and quantity of the product are related to the purity and yield of the product. Then add reagents that can lead to the formation of imino groups, control the temperature and time of the reaction, and make the two react moderately. If the temperature is high, the reaction will be fast, but it may be a by-product; if the temperature is low, the reaction will be slow, time-consuming or long. At this stage, the reaction process needs to be carefully observed, which can be observed by instruments, such as chromatographs, to show the degree of reaction.
When the reaction of imino group formation is completed, add the raw materials that can promote the construction of pyrimidine ring, and introduce an appropriate amount of oxygen substitution reagent, so that it can react under a suitable environment to form a 4-oxo-4,6-dihydropyrimidine structure. This step also requires strict control of conditions, such as pH, temperature and reaction time. The acid-base imbalance, or the reaction is biased, and the desired structure is not obtained; the duration is improper, or the reaction is incomplete, or the product is deteriorated due to excessive reaction.
After obtaining the 4-oxo-4,6-dihydropyrimidine-5- [2- (4-cyano-2-thiazolylphenyl) ethyl] -6-imino structure, a cobalt-containing compound and a reagent that can provide a carboxyl group are added. Under specific conditions, cobalt and pyrimidine structures are complexed into the state of cobalt-dicobalt 2-carboxylate. In this step, attention should be paid to the valence state of cobalt and the coordination environment. The valence state of cobalt is different, and the complexation effect is different; the coordination environment is not good, or it is difficult to form a stable cobalt-dicobalt complex.
The whole process requires proficiency in operation, careful temperature control, time control, and quantity control, and after each step, it is appropriate to have purification steps to remove its impurities, so as to obtain a pure synthesis of (6E) -6-imino-5- [2- (4-cyano-2-thiazolylphenyl) ethyl] -4-oxo-4,6-dihydropyrimidine-2-cobalt carboxylate dicobalt.

(6E) -6-Amino-5- [2- (4-nitro-2-oxobenzyl) thiazole] -4-oxo-4,6-dienoic acid cobalt dicobalt, when hiding, need to pay attention to a lot.
This compound has a special chemical structure and properties, and its stability is crucial. At the storage temperature end, it is advisable to choose a cool place. If the temperature is too high, it may cause its chemical structure to mutate, trigger adverse reactions such as decomposition, and damage its quality and activity. Generally speaking, it is better not to exceed 25 ° C.
Humidity is also a key factor. This substance may be sensitive to moisture and is easily deliquescent in case of moisture, which in turn affects its purity and performance. Therefore, it should be stored in a dry place. A desiccant can be used to maintain a dry environment, and the relative humidity should be maintained at 40% -60%.
Under light, this compound may cause photochemical reactions and cause structural changes. Therefore, when storing, avoid direct light, it should be stored in a brown bottle or opaque container, and stored in a dark place.
In addition, the storage place should be kept away from fire sources, heat sources and strong oxidants. Because of its active chemical nature, in case of such substances, or a violent reaction, causing dangerous accidents. At the same time, it should be placed separately from other chemicals to prevent mutual contamination and reaction. During handling and storage, the operation must also be careful, and the packaging should be handled with care to prevent damage and material leakage.
