4-Boron-indole-3-carboxylic acid is an organic compound with unique physical properties, which is very important in the field of organic synthesis and medicinal chemistry. Its physical properties are described as follows: 1. ** Properties **: This compound is mostly in the state of off-white to light yellow crystalline powder under normal conditions, which is easy to identify and handle in laboratory and industrial environments. 2. ** Melting point **: The melting point range is usually between 230-235 ° C. Melting point is a key physical property and can be used for purity identification. If the sample purity is high, the melting point should be within this narrow range; if it contains impurities, the melting point will be reduced and the melting range will be widened. 3. ** Solubility **: 4-boron-indole-3-carboxylic acid exhibits some solubility in common organic solvents such as dichloromethane, N, N-dimethylformamide (DMF) and dimethyl sulfoxide (DMSO). In dichloromethane, due to the van der Waals force and weak interaction between the molecule and the solvent, moderate dissolution can be achieved, which is conducive to the reaction substrate or intermediate in organic synthesis reactions. In polar aprotic solvents such as DMF and DMSO, the solubility is better, which is due to the formation of hydrogen bonds and dipole-dipole interactions between the solvent and the compound. However, its solubility in water is poor, because the hydrophobic part of the molecular structure accounts for a large proportion, and the interaction with water molecules is difficult to overcome the hydrophobic force. 4. Stability: The compound is relatively stable under normal conditions, but sensitive to humidity and air. In humid environments, boric acid groups may undergo reactions such as hydrolysis, which affect their chemical structure and properties. Therefore, it is necessary to keep it dry during storage. It is often recommended to operate and store in an inert gas (such as nitrogen or argon) atmosphere to maintain its stability and purity.

4-Quinolinesulfonic acid is an important chemical compound with polymorphism. It is acidic, because the molecular group can produce molecules. In aqueous solution, the atoms on the group can be partially decomposed, resulting in a weakly acidic solution. This acidity makes it possible to generate neutralization and reaction, resulting in a phase. 4-quinolinesulfonic acid also has the ability to coordinate. The presence of the quinolinesulfonic acid group makes it possible to make a ligation, and to form a ligand with solitary gold. With this property, it can be used as a gold complex, and the resulting complex is effective in catalysis, materials science, and other fields. In addition, 4-quinolinesulfonic acid has certain oxidative properties. Some of the functionalities in the molecule can be oxidized or reactive under the appropriate conditions. Under the action of specific oxidation, the group or other active sites can be oxidized to derive different oxidized compounds; on the contrary, when encountering the original properties, it can also be reactive and reactive, so that the molecule can be modified. Furthermore, it has photophysical properties. When irradiated with light, the molecule of 4-quinolinesulfonic acid can absorb light of specific waves, generate light, and form a phosphorescent or phosphorescent image. This property makes it have important uses in optical materials, biological imaging, etc. For example, it can be used as a photoprobe, used for specific substances in biological systems. Its chemical properties are also influenced by the substituents. If there are different substituents at other positions in the molecule, its acidity, coordination ability, oxidative properties and photophysical properties can be modified. For example, the introduction of molecular or absorber groups can change the density distribution of molecular subclouds, and the chemical properties can be controlled to varying degrees.

The synthesis of 4-keratosterol is an important component of the fungal membrane, and its synthesis process is exquisite. It has not been described in "Tiangong Rubber", but it can be deduced from the ancient production and fabrication techniques. Fungi synthesize keratosterol, starting with acetyl-CoA. This dicarbon element is polyphenylated to form methylvaleric acid. A series of reactions such as phosphorylation of methylvaleric acid and carboxylic acid are reversed, and pentene pyrophosphate (IPP) and its dimethylallyl pyrophosphate (DMAPP) are synthesized. These two phases increase carbon for three times to form farnesyl pyrophosphate (FPP). Molecular FPP is joined tail-tail to form a 30% carbon atom keratene. Keratene is oxidized to form lanosterol under the action of oxygenase. Lanosterol is then enzymatically reacted in multiple steps, including methyl removal, carboxylation, and carboxylation, etc., and gradually modified to form keratosterol. Ancient wine, wine is rich in polyfungi. In the production of koji, fungi multiply, and it is necessary to synthesize keratosterol to hold the cell membrane. The ancients did not know its chemical reaction, but they knew that the production of koji required specific materials and environments, and the ratio of materials was also studied. Among them, the fungus synthesizes keratosterol according to the above method under the appropriate conditions, so as to ensure its normal generation and proliferation, so that the wine can be profitable and the taste can be obtained. The same is true for the cultivation of fungi for use. It is necessary to create an appropriate environment for the fungus to synthesize keratosterol according to the inherent method to ensure its activity.

If there is a sulfuric acid, it is necessary to pay attention to the situation when it is hidden. The place where the sulfuric acid is stored is the first place. It is advisable to be in a dry and well-connected place, and avoid the dark place where the tide is. If it is in a tidal environment, sulfuric acid is easy to interact with water vapor phase, or cause it to have a low degree, and the tide is easy to cause the damage of the container. The container is also careful, and it is made of corrosion-resistant materials, such as glass and special plastic materials. Gold containers must not be used. Because sulfuric acid is corrosive, the gold is easy to cause chemical reactions, causing the container to break and the sulfuric acid to leak. This is a huge danger. The place where it is hidden is also a source of fire and heat. Sulfuric acid is non-flammable, and when it encounters high temperature, it may be melted or damaged, and the high temperature may also promote the reaction of the surrounding materials, endangering safety. At the same time, it should be stored in combustible, explosive, oxidizing and other materials to prevent accidental chemical reactions. Until the end of the year, the package must be packed. The container must be well sealed, and the outer layer should be equipped with protective materials to prevent collision and shock from causing the container to malfunction. The container should also be cleared of dryness, and it should be equipped with emergency treatment materials, such as adsorption materials, neutralization, etc., so as not to worry. People are also affected by the problem, and they are familiar with the urgent treatment methods of sulfuric acid. On the way, it is advisable to avoid severe bumps, emergency treatment, etc., to keep the transportation level, and avoid the danger caused by shaking. If it is a densely populated area or a water source, extra care should be taken to prevent leakage and pollute the environment, endangering the safety of the people. In addition, the storage of sulfuric acid is not easy, and everyone is worried about it.
