3 Iodo 5 Methylcinnamonitrile

3-Pentyl-5-methylfuranoic acid is an organic compound. Although the traditional process involved in "Tiangong Kaiwu" is not explicitly stated, its chemical properties can be discussed according to the current chemical understanding.
This compound has a furan ring, and the stability of the ring is weaker than that of the benzene ring. Under certain conditions, such as strong oxidants or high temperatures, the furan ring may be destroyed. Because it contains carboxyl groups, it has the commonality of carboxylic acids. The carboxyl group is acidic, and can weakly ionize hydrogen ions in water. It can neutralize with bases, such as reacting with sodium hydroxide to form corresponding carboxylate and water.
And because it has alkyl groups, it has certain hydrophobicity. The existence of alkyl groups makes the compound more soluble in organic solvents than in water. In the field of organic synthesis, carboxyl groups can participate in a variety of reactions, such as esterification with alcohols, and acid catalysis to form esters and water. This reaction is an important way to prepare ester compounds.
At the same time, the difference in the distribution of electron clouds between different atoms in the compound makes it possible to undergo nucleophilic substitution or electrophilic substitution, depending on the reaction conditions and reagent characteristics. The diversity of its chemical properties determines its potential application in organic synthesis, pharmaceutical chemistry and other fields. It can be used as an important intermediate in the synthesis of complex organic molecules, providing a basis for the creation of new drugs and new materials.

It can promote cell regeneration, enhance the body's self-repair ability, and allow the pain to heal as soon as possible and return to normal life.

The book "Tiangong Kaiwu" says: "To make 5-aminovaleric acid (α-aminovaleric acid or valine), you need to start with valerian, and you need to go through several wonderful methods to obtain this treasure."
Take the root of valerian first, wash it, and crush it with a stone pestle to form a mud. Then, put it in a kettle, add an appropriate amount of water, and cook it slowly. When the juice is amber, stop the fire. Pour this juice into a fine sieve, filter out the dross, and leave the clear liquid.
The clear liquid contains the essence of valerian, but if you want to obtain valine, you need to further change. Take the clear liquid, add an appropriate amount of lime powder, stir well, and see that its color is gradually turbid, and there is precipitation. This precipitator is the combination of valine and lime.
Filter it with cloth to get the precipitation. Then put the precipitation in another kettle, add dilute sulfuric acid, and stir moderately. The sulfuric acid reacts with the calcium salt in the precipitation, and the valine is re-released and dissolved into the liquid.
Then by distillation, remove the excess water. Watch the liquid gradually concentrate, and when there is a crystal nucleus, move the kettle to a cool place and wait for crystallization. After a long time, the crystal of valine gradually forms, shining like broken jade, and this is the finished product of valine.
The whole process requires caution step by step, and the temperature and dosage are all about success or failure. Although the ancient techniques are simple, they contain the principles of heaven and earth creation, and are also the first for amino acid production in later generations.

In today's market, the price of five-grade beef jerky varies according to various feelings. The source of Guanfu's ingredients, the best beef, is taken from strong cattle, its quality is fresh and tender, the jerky meat is delicious and of high quality, and the price must be high. If the cow is sick and the meat is weak, the price of the jerky is low.
Furthermore, the complexity of the craftsmanship is also related to the price. Refined jerky meat, the selection of materials is strict, and the method of processing is delicate. First, it is marinated with secret ingredients, so that the spices penetrate into the texture, and then it is slowly roasted. The heat is exquisite, and its taste is mellow and fragrant. Such jerky meat is expensive in the market. The coarse ones, the materials used are not refined, the process is simple, the taste is light, and the price is low.
The difference in origin also makes the price different. If it is produced in a place that is good at making dried meat, its method has been passed down for a long time, the craftsmanship is skilled, the reputation is far-reaching, and the price is often high. Those who imitate it elsewhere, although they follow its shape, the flavor is difficult to reach, and the price is slightly inferior.
And the supply and demand of the city are also the key. During the festive season, everyone wants to buy dried meat as a gift, and the demand is large, and the price may rise. In normal times, there are few people in need, and merchants sell it quickly, or reduce their price.
As far as it is concerned, the price of Wujia beef jerky ranges from tens to hundreds of dollars per catty. The fine one is expensive, and the rough one is cheap. Buyers should choose it carefully according to their own good and strength.

The third -%E7%A2%98-5-%E7%94%B2%E5%9F%BA%E8%82%89%E6%A1%82%E8%85%88, during storage and transportation, there are several ends that should be paid attention to.
The first temperature control. This product is quite sensitive to temperature, too high is perishable, too low or damage its quality. Therefore, when storing, it is advisable to choose a suitable temperature area, often [X] to [X] degrees Celsius, so as to maintain the stability of its properties and extend its shelf life. During transportation, it should also be accompanied by temperature-controlled equipment to prevent sudden changes in temperature.
The second is the adjustment of humidity. If the humidity is too high, it is easy to breed mold and cause mildew; if the humidity is too low, it may lose water and deteriorate the texture. Where it is stored, the humidity should be maintained between [X]% and [X]%. When transporting, it should also be moisture-proof and moisture-proof. Moisture-proof packaging materials can be used, and it should be protected from moisture.
Furthermore, the packaging must be solid and suitable. Strong packaging can protect it from collision and extrusion during transportation. And the packaging material should be clean, non-toxic, and not harmful to this product. It should also be easy to handle and stack to improve the efficiency of storage and transportation.
Also, the light should not be ignored. If this product is exposed to strong light for a long time, its composition may be damaged and the quality will be degraded. Therefore, it is suitable for storage in a cool and dark place. When transporting, it should also be shielded by a mask to avoid contact with strong light.
Again, the environment for storage and transportation must be clean and odor-free. Odor may enter this product, causing its odor to be incorrect; in an unclean environment, it is easy to stain bacteria and endanger quality.
In addition, during storage and transportation, it is advisable to set up regular inspections. Observe whether it has any signs of deterioration, check whether the packaging is damaged, and whether the temperature and humidity are properly controlled. If there is any abnormality, dispose of it as soon as possible to avoid loss expansion.
