To prepare 2,4,5,6-tetraaminopyrimidine sulfate, the following method can be used:
First take the corresponding pyrimidine compound as the starting material. Usually start with 2,4,5,6-tetrachloropyrimidine, because chlorine atoms are active and easy to be replaced by amino groups. Place 2,4,5,6-tetrachloropyrimidine in a suitable reaction vessel and dissolve it in a suitable organic solvent, such as dimethylformamide (DMF) or dichloromethane, etc. This organic solvent needs to be able to dissolve the reactants well and have no adverse effects on the reaction.
Then add an excess ammonia source, such as liquid ammonia or concentrated ammonia water. Ammonia reacts with chlorine atoms in tetrachloropyrimidine in a nucleophilic substitution reaction. During the reaction, the reaction temperature and time need to be controlled. The temperature should not be too high, otherwise it may cause an increase in side reactions, usually controlled in the range of low temperature to room temperature, such as between 0 ° C and 30 ° C. The reaction time depends on the monitoring of the reaction process. Generally, it takes several hours to ten hours. The reaction can be monitored by thin layer chromatography (TLC) and other means. When the raw material point is basically eliminated, it indicates that the reaction is roughly completed.
After the reaction is completed, the reaction mixture is post-treated. The organic solvent is first distilled under reduced pressure to remove, and then the residue is dissolved in water. At this time, the product exists in the form of ammonium salt in the aqueous solution. After that, the dilute sulfuric acid solution is slowly added dropwise and adjusted to an appropriate pH value to make 2,4,5,6-tetraaminopyrimidine sulfate precipitate. This process requires attention to the regulation of pH value, because peracid or peralkali may affect the purity and yield of the product.
Finally, the precipitated precipitate is filtered, washed with an appropriate amount of cold water to remove impurities, and then dried in vacuum to obtain a pure 2,4,5,6-tetraaminopyrimidine sulfate product. The entire preparation process requires attention to the precise control of reaction conditions and the fine operation of post-treatment to achieve ideal results.

2% 2C4% 2C5% 2C6-tetrahydroxybenzoquinone. When storing and transporting this substance, many matters need to be paid careful attention.
Its nature is delicate, light-phobic and heat-phobic. Under light, it is prone to photochemical reactions, causing structural changes and activity attenuation. Therefore, when storing, choose a cool and dark place and hold it in a dark container to prevent light intrusion. Heat is also its enemy. High temperature will promote its decomposition and deterioration. The temperature of the warehouse should be controlled in a specific range, not too high.
Furthermore, 2% 2C4% 2C5% 2C6-tetrahydroxybenzoquinone is corrosive to a certain extent, touching human skin and mucous membranes, or causing burns. The operator must wear protective equipment, such as gloves, goggles, protective clothing, etc., and strictly refuse to come into direct contact with it. If you accidentally touch it, you should quickly rinse it with plenty of water and seek medical attention immediately.
During transportation, its stability cannot be ignored. It should be ensured that the packaging is tight, shockproof and leak-proof. If the packaging is damaged and the drug leaks, it will not only damage the drug itself, but also endanger the surrounding environment and personnel safety. And the conditions of the transportation vehicle also need to be adapted, and the temperature and humidity should meet the requirements to avoid bumps and vibrations and ensure the quality of the drug.
In addition, 2% 2C4% 2C5% 2C6 -tetrahydroxybenzoquinone may react chemically with other substances. During storage and transportation, do not mix with reducing substances, acidic or alkaline substances to prevent violent reactions and cause safety risks.
In short, the storage and transportation of 2% 2C4% 2C5% 2C6 -tetrahydroxybenzoquinone requires all-round consideration of light, heat, corrosion, packaging and reaction factors, and be careful to protect its quality and ensure safety.
