In addition, 5-hydroxy- 3-indole acetic acid participates in many physiological processes in plants, and its chemical properties are closely related to its physiological functions. It can regulate the elongation, division and differentiation of plant cells, and affect the growth and development of plants. Physiological phenomena such as stem elongation, root growth, phototropism and gravitropism are all closely related to it. Due to the stability of its chemical structure and moderate reactivity, it can precisely perform its physiological regulation functions in plants.

The use of 5-3-pentenoic acid (9CI) has its own impact in the fields of engineering, chemical synthesis, materials, etc.
In the field of chemical synthesis, it is important in the synthesis of chemical compounds. It can be synthesized by a series of reactions, and compounds with specific biological activities can be synthesized. For example, in the synthesis of some cardiovascular disease drugs, 5-3-pentenoic acid can be used as one of the starting materials, functionalization, molecular construction, etc., and the most effective way to improve blood lipids and improve cardiovascular function.
In the field of chemical synthesis, it is not used in the synthesis of other chemical compounds, but also used in the construction of carbon skeletons. Due to its high molecular activity, such as esterification, nucleation, addition, and so on, it is possible to synthesize different types of compounds. For example, the esterification reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction, such as acrylate reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction reaction.
Therefore, 5-3-pentenoic acid plays an indispensable role in many important domains due to its unique molecular reaction activity, promoting the development of technology, chemistry, and materials.

The synthesis method of 5-3-pentenoic acid (9CI) has a long way to go. One can be the alkenylation of alkenes. First, the alkenylated substrate is taken, and under the appropriate reaction, specific catalysis and oxidation are used to promote the alkenylation of alkenylenes, and then the alkenylenyl group is introduced, and then the alkenylenylenyl group is functionalized and the whole molecule is formed. In order to obtain 5-3-pentenoic acid.
Furthermore, it can be started from a compound containing carbonyl groups. If there are suitable alters or ketones, by the reaction of alkenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylenylen
Or it can be used as a reaction of gold. With the reaction of gold or gold, etc., the reaction of carbon or carbonyl compounds is replaced, and the molecular skeleton is gradually built, and the reaction of 5-3-pentenoic acid is introduced.
In the synthesis, pay attention to the precise control of reaction parts, such as resistance, resistance, reaction, etc., all of which have a crucial impact on the reaction rate and performance. And the proportion of reaction matter and the degree of reaction in each step are properly considered, so as to obtain the ideal synthesis effect.

In today's market, the price of 5-hydroxy-3-indoleacetic acid (9CI) varies depending on the quality, origin, supply and demand. For ordinary people, the price is between tens of gold and hundreds of gold per gram. If it is a refined product or a famous product, the price is higher, and the price can reach more than a thousand gold per gram.
However, the market is impermanent, and the price moves with the trend. If the demand for this product increases sharply and the supply is limited, the price will rise; on the contrary, if the supply exceeds the demand, the price will decline. Therefore, if you want to know the exact price range, you must carefully observe the current market conditions and consult with various merchants before you can get it. Although it can be roughly known that the price is in the range of tens of gold per gram to thousands of gold per gram, the actual price is ultimately subject to what is heard and seen in the market, and cannot be generalized.

5-% -3- to its acetic acid (9CI), the hidden parts have been studied. This layer needs to be kept in a dark and dry place, and its properties are susceptible to loss and loss.
If the loss is high, it may make the change. For example, in the summer, if the room is full of loss, under high exposure, the activity of its molecules may increase, resulting in decomposition, polymerization and other reactions, and its effectiveness. Therefore, it should be stored in a place where the loss is fixed and low, in order to ensure its safety.
The degree also needs to be improved. This 5-% -3- to its acetic acid (9CI) is easy to absorb when exposed to moisture, absorb it, or cause it to change its shape, such as from the dry powder particles, or even sticky. And in the tidal environment, it is easy to breed bacteria,. Therefore, it must be hidden in the dry, or in the storage device, in order to absorb the dry.
It is also necessary to avoid direct light. The energy of light can be reversed, so that its active ingredients can be degraded. If it is placed in a place with intense light such as in front of a window, it will lose its effect when the sun is tired. It is appropriate to hide it in a dark room or use a shading device.
Therefore, in order to protect the efficacy of 5-%-3-acetic acid (9CI), it is indispensable to store dark, dry and dark items.
