A detailed introduction to 3-indolebutyric acid

In the field of chemistry, there is a substance that attracts much attention - 3-indolebutyric acid. It has several different names, which are both called indolebutyric acid and indolebutyric acid. Judging from its molecular structure, its molecular formula is C11H12O2N. Through precise calculation, we can know that its molecular weight is 190.22.

When we see the pure 3-indolebutyric acid product, we will find that it presents the form of a white crystalline solid. Under specific experimental conditions, its melting point is within the range of 124-125℃. However, in the industrial production process, due to the influence of various factors, industrial products will present a state of white to light yellow crystals, and their melting points are also slightly different, ranging from 121 to 124°C. This substance has a special smell, which is unique and easily recognizable. It should be particularly noted that it is toxic and has a certain degree of irritation to the human body and the environment. Therefore, extra caution is needed during contact and use.

In terms of physical properties, the vapor pressure of 3-indolebutyric acid is less than 10μPa at 60℃. It has poor solubility in water and is insoluble in it. Specifically, at an ambient temperature of 20℃, its solubility in water is only 0.25g/L. However, it has good solubility in organic solvents, is readily soluble in benzene, and is also soluble in many other organic solvents. Its solubility in different organic solvents (g/100ml) is as follows: approximately 100 in benzene; It is 3-10 in acetone, ethanol and ether. It is approximately 10 in chloroform

It is worth mentioning that 3-indolebutyric acid has relatively low toxicity to humans and animals, which to a certain extent reduces the potential risks it may bring during use. It also has the property of being stable to acids and can form salts in solutions of alkali metal hydroxides and carbonate compounds. From the perspective of chemical synthesis, it can be obtained from indole through the Grignard reaction or hydrolysis with nitriles.

In the field of agriculture, 3-indolebutyric acid has significant application value. It can serve as an effective plant growth promoter and play a positive role in promoting the growth and development of plants. Specifically, it can promote the growth of plant roots, making the roots of plants more developed, thereby enhancing the plants' ability to absorb water and nutrients. Meanwhile, it can also promote the ripening of fruits, allowing them to enter the ripening period earlier and enhancing the quality and yield of the fruits. Moreover, its effect is stronger than that of indoleacetic acid, which gives it a greater advantage in agricultural production.

For instance, during the cutting process of cherry rootstocks, indolebutyric acid is an excellent growth regulator. For the treatment of rock cuttings, methods such as high-concentration rapid impregnation or soaking can be adopted. Among them, the high-concentration rapid impregnation method is a relatively common and efficient approach. The specific operation is to immerse the base of the rock cuttings in a solution with a concentration of 5× 10-4 to 1× 10-2 IBA for 5 seconds, and then immediately insert the rock cuttings into the cutting machine. This method has many advantages. Firstly, the processing time is relatively short, enabling the processing of rock cuttings to be completed within a short period of time and improving work efficiency. Secondly, uniform drug administration can ensure that all parts of the rock debris can fully come into contact with the drug, thereby enabling the drug's effect to be fully exerted. Finally, the treatment effect is good and it can significantly increase the rooting rate of rock cuttings.

Furthermore, if 20.375 g/m of simmarazine is added to the cutting bed, the rooting rate of the cuttings will be higher. This means that through reasonable drug combinations and treatment methods, the growth conditions of plants can be further optimized, and the survival rate and growth quality of plants can be improved.

In the wonderful world of plant growth, plant growth regulators play a crucial role. Among them, there is a kind of plant growth regulator. When plants are treated with a liquid with a concentration of 0.001% to 0.0001%, it can significantly promote the rooting of many tree and flower cuttings. This magical phenomenon undoubtedly holds extremely significant importance for the massive reproduction of seedlings and flowers. It should be known that in horticulture and agricultural production, the massive reproduction of seedlings and flowers has always been a key link, and this plant growth regulator is like a magical key, providing strong support for solving the reproduction problem. However, when using this regulator, special attention should be paid. It should not be directly applied to plant leaves to avoid adverse effects on plant growth.

Among numerous plant growth regulators, indolebutyric acid (IBA) stands out. It is a broad-spectrum indole plant growth regulator and also an excellent rooting agent. Whether it is the alluring herbaceous ornamental plants or the upright woody ornamental plants, indolebutyric acid can play its unique role when propagating by cuttings, effectively promoting the rooting of the cuttings. Moreover, its functions are not limited to this. During the fruit setting stage of plants, indolebutyric acid can also play a significant role. By regulating the physiological functions of plants, it can effectively increase the fruit setting rate and make the fruits more abundant.

After years of practical tests, synthetic indole-3-butyric acid has been proven to be a highly efficient, low-toxic, highly active, broad-spectrum and pollution-free biochemical preparation due to its outstanding performance. During the growth process of plants, it is like an all-round "assistant", not only an excellent plant growth regulator that can precisely control the growth rhythm of plants; It is also a highly effective rooting agent, providing powerful support for the development of plant roots. At the same time, it is also a promoter for the growth of fruits and vegetables, enabling them to grow more vigorously during the growth process, significantly increasing the fruit setting rate and bringing substantial profits to agricultural production.

From the perspective of plant physiology, indole-3-butyric acid belongs to a hormone of the plant auxin family. In the complex physiological metabolic processes within plants, IBA is regarded as the precursor of indole-3-acetic acid (IAA). IAA, on the other hand, is the most abundant natural auxin in plants, functioning like a "commander" within the plant. It generates the majority of auxin effects in a complete plant and is the most effective natural auxin, exerting a crucial influence on various aspects of plant growth and development.
