Calcium 4-Hydroxyisobutyrate (1:1) is commonly used in three ways. One is in the field of medicine and can be used as a calcium supplement. Calcium, an essential element for the human body, is related to the strength of bones and teeth, and plays an important role in many physiological functions such as nerve conduction, muscle contraction and relaxation. Calcium 4-Hydroxyisobutyrate (1:1) is easier to absorb by the human body due to its unique chemical structure, which can help the human body maintain normal calcium levels. Therefore, it is effective in preventing and treating calcium deficiencies, such as rickets and osteoporosis.
Second, in the food industry, this substance can be used as a nutritional enhancer. Nowadays, people are paying more and more attention to healthy eating, and food manufacturers often add various nutritional fortifiers to increase the nutritional value of food. Calcium 4-hydroxyisobutyrate (1:1) added to food can increase the calcium content of food, making it more suitable for consumers' pursuit of health. It is common in dairy products, cereal products, beverages and many other food categories.
Third, in the feed industry, calcium 4-hydroxyisobutyrate (1:1) also has its place. When livestock and poultry grow and develop, an adequate supply of calcium is indispensable. Adding this substance to feed can effectively meet the calcium needs of livestock and poultry, promote their bone development, enhance their physical fitness, improve their disease resistance, and then improve the efficiency of breeding. It is quite commonly used in the field of animal husbandry.

To make allyl 4-hydroxyisobutyrate (1:1), you can follow the following ancient method:
First take an appropriate amount of isobutenic acid and place it in a clean kettle. Take an ice water bath and slowly lower its temperature to a suitable low temperature, between about 0 ° C and 5 ° C. At this low temperature state, add propylene oxide dropwise, and the speed of dropwise addition must be uniform and slow, so that the two can be fully integrated. This process requires careful temperature control, and the temperature should not fluctuate greatly to prevent side reactions.
After adding the propylene oxide dropwise, remove the ice water bath, so that the mixture in the kettle gradually rises to room temperature, and then continue to stir at this temperature to promote its complete adaptation. This step should take a long time, or several hours or even more than a day, depending on the situation in the kettle. When it should be done well, the stirring should be stopped.
Next, take an appropriate amount of allyl alcohol and add it to the kettle with the catalyst. The choice of catalyst is p-toluenesulfonic acid or the like, and the amount depends on the amount of isobutylene acid, which is about 1% to 3% by mass of isobutylene acid. After adding it, heat it up to 60 ° C to 70 ° C, and reflux the reaction at this temperature. In the meantime, a condenser is required to re-condense the dissipated gas into a liquid and return it to the kettle to ensure that the material is not damaged.
When refluxing, closely observe the situation, and take an appropriate amount of samples to measure the process by thin-layer chromatography. When the raw materials are exhausted and the product reaches the expected purity, stop responding.
After the reaction is stopped, pour the liquid in the kettle into the separation funnel and wash with an appropriate amount of saturated sodium bicarbonate solution to remove the acid and catalyst. Discard the lower aqueous phase, and dry the upper organic phase with anhydrous sodium sulfate to remove the water.
Finally, the product is refined by vacuum distillation. Control the pressure and temperature of distillation, and collect the fraction with a specific boiling range, which is the finished product of 4-hydroxyisobutyrate propyl ester (1:1). The boiling range is about 100 ° C to 110 ° C/1.33kPa, and the finished product needs to be properly stored, protected from light, high temperature and humidity, to ensure its purity and stability.

4-Deuterium-pentene photooxalic acid (1:1), where it is hidden, pay attention to things like this.
If you hide it, it is the dryness of the first environment. This compound is easy to initiate and dissolve in case of tide, so it should be placed in a place where the dryness is common, and it should be avoided in a place where the dryness is common. If it is placed in a place where the tide is high, it should not be invaded by water, and its chemical properties will be changed, resulting in the loss of its original efficacy.
And the degree should also be changed. Avoid high places, because it is easy to decompose. It should be stored in cool places. Generally speaking, it is better to keep the temperature between five and twenty-five degrees. If the temperature is high, the molecular activity will be strong, and the melting will be easy to crack, so the material will be damaged.
Furthermore, the hidden container should not be ignored. It should be made of corrosion-resistant and well-sealed materials. Due to the reaction of 4-deuterium-pentene photooxalic acid (1:1) or some materials, glass, special plastics, etc. should be placed on the container, and the seal must be made to prevent the components in the air from being connected and eroded.
As far as the environment is concerned, earthquake resistance is the top priority. This material is fragile or fragile. If it is rough on the way, it may cause the container to break and the material to be exposed. Therefore, the construction of the product should be smooth, and the material should be firmly placed. The surrounding area can be placed with other materials, such as foam and foam, so as to shock.
It is also necessary to avoid sources of danger such as fire and coal sources. 4-deuterium-pentene photooxalate (1:1) may be flammable or other dangerous, and it is easy to cause damage in case of fire or magnetic damage. And people are also affected by the problem. They are familiar with the characteristics of this material and the method of emergency treatment. As soon as there is an accident such as exposure, they can be properly treated to ensure safety.

Wen Jun inquired about the market price range of calcium 4-hydroxyisobutyrate (1:1). According to the relevant information of this drug, the price of the market often varies for many reasons. The source of its production, the essence of technology, and the situation of supply and demand are all causes of change.
In the market, if the production source is wide and the process is good, the supply is sufficient and the demand is flat, the price may tend to be easy. However, if the production source is thin, the process is difficult, and there are many applicants, the price will rise.
According to the past market conditions and the industry, the price of calcium 4-hydroxyisobutyrate (1:1) fluctuates between tens of dollars and hundreds of dollars per unit. However, this is only an approximate number, and the actual price should be determined according to the current market conditions, the amount purchased, and the specific circumstances of the transaction. To know the exact price, you need to consult pharmaceutical companies, pharmaceutical merchants, or observe the real-time price between the markets before you can get it.
