The physicochemical properties of 1- (4-aminophenyl) -1H-pyrazole are related to the physical and chemical properties of this compound. Among its physical properties, appearance is often the key characteristic. 1- (4-aminophenyl) -1H-pyrazole is usually solid, which causes the molecules to be closely arranged due to intermolecular forces. As for the color, or white to light yellow powder, the appearance of this color is due to the absorption and reflection properties of the molecular structure.
Its melting point is also an important physical property. After experimental determination, the melting point of the substance is in a specific temperature range, and this temperature value reflects the strength of the interaction between molecules. When the temperature reaches the melting point, the molecule obtains enough energy to overcome the interaction force, thereby transforming from a solid state to a liquid state.
In terms of solubility, 1- (4-aminophenyl) -1H-pyrazole may have a certain solubility in organic solvents such as ethanol and dichloromethane, but its solubility in water may be low. This difference in solubility is related to the polarity of the molecule, and the molecular structure of the compound makes it more prone to interact with organic solvent molecules.
On its chemical properties, both the amino group of 1- (4-aminophenyl) -1H-pyrazole and the pyrazole ring are reactive. Amino groups can participate in many reactions, such as salt reactions with acids to form corresponding salt compounds. Pyrazole rings can also participate in electrophilic substitution reactions, because of the distribution of electron clouds on the ring, making specific locations vulnerable to electrophilic agents. In addition, under appropriate conditions, the compound may undergo oxidation, reduction, etc., depending on the nature and strength of the oxidizing or reducing agent in the reaction system.

The synthesis method of 1- (4-aminophenyl) -1H-pyrazole is an important topic in the field of chemistry. The synthesis method has many different paths, which can be achieved by a variety of starting materials and various reaction steps.
One of the common methods is to start with a benzene derivative containing a specific substituent. After the condensation reaction with a suitable nitrogen-containing reagent under specific reaction conditions, the intermediate containing benzene ring and nitrogen atom is initially obtained. This condensation reaction requires precise regulation of the reaction temperature, time and ratio of reactants to obtain the ideal yield.
Furthermore, the obtained intermediate can be cyclized. By selecting the appropriate catalyst and reaction solvent, the cyclization of the molecule is promoted to construct the structure of the pyrazole ring. This cyclization process is related to the selectivity of the reaction and the purity of the product, and the reaction conditions must be carefully controlled to prevent side reactions from occurring.
also takes another idea, starting from the simple compound containing the prototype of the pyrazole ring. First, it is modified with substituents, and 4-aminophenyl is gradually introduced into the molecular structure. This process requires clever use of various organic reactions, such as nucleophilic substitution and electrophilic substitution. During nucleophilic substitution, attention should be paid to the activity of the leaving group and the strength of the nucleophilic reagent; for electrophilic substitution, the effect of the electron cloud density of the benzene ring on the reaction check point should be considered. < Br >
During the synthesis process, the products of each step of the reaction need to be strictly separated and purified. Methods such as column chromatography and recrystallization can be used to ensure the purity of the products and lay a good foundation for subsequent reactions. And after each step of the reaction, analytical methods such as nuclear magnetic resonance and mass spectrometry must be used to confirm the structure of the products to ensure the correctness and feasibility of the synthesis route.

The price range of 1- (4-aminopyridine) -1H-pyrazole in the market is quite difficult to determine. The price of this product often varies for many reasons.
First, it is related to the purity and complexity of the quality. If the quality is extremely pure and almost flawless, its price will be high; if it contains a little more impurities, the price will drop. Second, it depends on the amount of production. If there are many producers, the market supply is abundant, and the price may be flat; if there are few producers and many people are seeking, the price will rise. Third, it depends on the difficulty of making. If the preparation technique is complicated, labor-intensive and time-consuming, and there are many consumables, the cost will be high, and the price will not be low; if it is easy to make, the cost will decrease, and the price will follow.
Basically speaking, the price of this 1- (4-aminopyridine) -1H-pyrazole per gram may be between tens of dollars and hundreds of dollars. If the amount is large, a slight discount may be obtained, and the price may be slightly reduced. However, this is only an approximate number. The market conditions are ever-changing, and the actual price should be confirmed by consulting the merchants, vendors or industry in the market from time to time.

1- (4-aminopyridine) -1H-pyrrole should be noted during storage and transportation:
First, both of these are organic compounds and are quite sensitive to temperature and humidity. If the temperature is too high, it may cause chemical reactions or even deterioration; if the humidity is too high, or the substance is damp, it will affect its purity and performance. Therefore, when storing, it should be placed in a cool, dry place, away from heat and water sources.
Second, 1- (4-aminopyridine) -1H-pyrrole has a certain chemical activity, and may cause violent reactions when exposed to oxidants, strong acids, strong bases and other substances. When storing and transporting, be sure to avoid mixing with such substances to prevent danger.
Third, both may have certain toxicity and irritation. Whether it is storage or transportation, protective measures must be taken. Operators should wear appropriate protective equipment, such as protective clothing, gloves, protective glasses, etc., to avoid direct contact. If inadvertently exposed, rinse with a lot of water immediately and seek medical attention in time.
Fourth, storage and transportation sites should be equipped with corresponding emergency treatment equipment and materials. For possible leaks, adsorbents, neutralizers, etc. are required to deal with them in a timely manner to prevent the spread of pollution and reduce hazards.
Fifth, strictly follow relevant regulations and standards. Whether it is the setting of storage conditions or the operation specifications during transportation, it should conform to the safety standards formulated by the state and the industry to ensure the compliance of the whole process and ensure the safety of personnel and the environment.
