1% 2C2-dimethyl-4-phenyl-1H-pyrazole This substance has many physical properties. Its appearance, at room temperature, is mostly a crystalline solid state, with a white color and fine texture, like finely crushed frost and snow, and has a certain luster, just like a pearl shimmering.
When it comes to the melting point, it has been strictly determined to be around a certain temperature range. When the temperature gradually rises near the melting point, this substance slowly changes from a solid state to a liquid state, just like ice and snow melting, initially only the edge softens slightly, and gradually the whole crystal turns into a flowing liquid.
In terms of boiling point, there are also corresponding values. In a specific pressure environment, when the temperature rises to the boiling point, the substance will boil violently, and a large number of molecules will break free from the shackles of the liquid phase and escape into a gaseous state, like cloud evaporation.
In terms of solubility, it exhibits a certain solubility in organic solvents. Organic solvents such as common ethanol and ether can partially dissolve this substance to form a uniform solution, just like salt dissolves in water and quietly fuses together. However, in water, its solubility is poor, just like oil floating in water, making it difficult to blend.
Density is also one of its important physical properties. By accurate measurement, its mass per unit volume can be known. This density characteristic determines its ups and downs in different media. If it is placed in a liquid with a different density, it will sink or float at a glance.
In addition, it also has certain stability. Under normal environmental conditions, it is not easy to chemically react with surrounding substances, just like a calm person, who is not easily disturbed by the outside world. However, under certain conditions, such as high temperature, strong acid and alkali, the stability will be challenged, or reactions such as decomposition and transformation will occur.

1% 2C2-dimethyl-4-phenyl-1H-pyrazole, although not detailed in "Tiangong Kaiwu", but according to the understanding of ancient techniques, its use may involve medicine and dyeing and weaving ends.
In the way of medicine, ancient doctors often explored the properties of ordinary plants, trees, gold and stones to treat diseases. This 1% 2C2-dimethyl-4-phenyl-1H-pyrazole, if it has specific pharmacological activity, may be included in pharmaceuticals. The ancient people studied the physical properties carefully and knew that some organic compounds have antibacterial and analgesic properties. Looking at ancient medical books, many different herbs and strange roots have been processed and combined, and they have all become a cure for diseases. Suppose this material has bacteriostatic effect, or can be used for sores, swelling and poison, and can be applied or taken internally to help the body resist evil poison.
As for the way of dyeing and weaving, ancient dyeers make good use of various natural and synthetic pigments to add color to fabrics. 1% 2C2-dimethyl-4-phenyl-1H-pyrazole If it has color or can help with pigment fixation, it must be a good material for dyeing and weaving. In ancient dyeing workshops, in order to make fabrics bright and lasting, they often looked for new things to try. If this material can increase the color fastness of the fabric and make the color bright, it will be favored by the dyer and used for dyeing silk and cloth materials for clothing, curtains, etc.

The synthesis method of 1% 2C2-dimethyl-4-phenyl-1H-pyrazole is not directly mentioned in "Tiangong Kaiwu", but it contains many chemical synthesis ideas, which can be inspired to deduce possible methods.
View the various chemical techniques described in "Tiangong Kaiwu", which involve material selection, control of reaction conditions and operation steps. By extension, 1% 2C2-dimethyl-4-phenyl-1H-pyrazole is synthesized, and the first material is selected. Compounds containing methyl and phenyl groups can be found as starting materials, such as halogenated hydrocarbons with active methyl groups and reagents containing phenyl groups. The two may be introduced into methyl and phenyl groups through nucleophilic substitution reactions.
The reaction conditions are also crucial. "Tiangong Kaiwu" often says that the influence of heat and time on the reaction, in the synthesis of this substance, precise temperature control may be required. Reactions at different stages may require a specific temperature range to promote the reaction in the desired direction. High temperature may accelerate the reaction, but it may also cause side reactions to occur; although low temperature can reduce side reactions, it may make the reaction rate too slow. Therefore, choosing the right temperature is very critical.
Furthermore, the operation steps need to be orderly and careful. The order of material mixing may affect the initiation and progress of the reaction. If some materials are mixed first, and after a certain reaction, other materials are added to avoid unnecessary side reactions. And during the reaction process, operations such as stirring may be required to promote full contact of materials and make the reaction uniform.
Although "Tiangong Kaiji" does not specify the synthesis of 1% 2C2-dimethyl-4-phenyl-1H-pyrazole, according to its chemical concept, from the three ends of materials, reaction conditions and operation steps, a feasible synthesis path can be explored.

1% 2C2-dimethyl-4-phenyl-1H-pyrazole This substance requires careful attention when storing and using.
First, it is related to storage. Due to its nature or being disturbed by the external environment, it is necessary to choose a dry, cool and well-ventilated place. If placed in a humid place, it may react with water vapor and cause it to deteriorate. And the temperature also needs to be strictly controlled. Excessive temperature may cause changes in its chemical structure and reduce its quality. At the same time, it should be kept away from fire and heat sources. Because it may be flammable, if it is close to the fire source, it is prone to fire risk. In addition, it needs to be stored separately from the oxidant, because its chemical properties are lively, coexist with the oxidant, or cause a violent reaction, endangering safety.
Second, about use. Be sure to read the relevant operating instructions and safety instructions carefully before use to clarify its chemical properties and latent risks. When operating, wear appropriate protective equipment, such as protective gloves, goggles, etc., to prevent it from contacting the skin and eyes, causing burns and other injuries. It is best to operate in a fume hood, so that the harmful gases that may be generated can be discharged in time, avoid inhalation into the body, and damage to health. Furthermore, the use process should strictly follow the specified dosage, and cannot be increased or decreased at will. If the dosage is too small, it may be difficult to achieve the desired effect; if the dosage is too large, it will not only be wasted, but also cause other unexpected reactions. After use, properly dispose of the remaining substances and do not discard them at will. They must be disposed of in accordance with relevant regulations to prevent environmental pollution.
