1 - (3 - amino) pyridine is an organic compound with the following physical properties:
In appearance, the normal state is a colorless to light yellow liquid, under certain conditions, or a crystalline solid. This state is affected by the ambient temperature and purity. At room temperature, if the purity is high, it may appear as a liquid; at low temperature, it may gradually crystallize and solidify.
Its odor is special and irritating, and it is uncomfortable to smell. When you get close to it, the irritation is more obvious. The odor is derived from its molecular structure and produces a stimulating effect on olfactory receptors.
In terms of solubility, it has a certain solubility in water. This is attributed to the fact that amino groups can form hydrogen bonds with water molecules, enhancing their affinity with water. However, due to the hydrophobicity of the pyridine ring, its solubility is not infinite, and it reaches a solution equilibrium after a certain degree. In addition to water, it is also easily soluble in organic solvents such as ethanol and ether. The molecular structure of ethanol and ether can interact with 1- (3-amino) pyridine, and it is uniformly dispersed in the solvent through intermolecular forces, such as van der Waals force and hydrogen bond.
The boiling point and melting point are crucial for the identification and separation of this compound. Its boiling point is about 254-256 ° C, and its melting point is about 28-30 ° C. The higher boiling point indicates that the intermolecular force is strong. To transform it from liquid state to gas state, more energy needs to be input to overcome the intermolecular attractive force. The melting point determines the temperature at which it transitions from solid to liquid, at which the state of matter changes.
1- (3-amino) pyridine has a density of about 1.069 g/cm ³, which is slightly higher than that of water. This means that in the case of immiscibility and stratification with water, it will sink to the bottom of the water. These physical properties provide an important basis for its application and operation in chemical, pharmaceutical and other fields.

1 - (3 - amino) pyridine is an organic compound, and the stability of its chemical properties is of great value.
In terms of structure, the pyridine ring is aromatic, and the presence of nitrogen atoms endows it with a specific electron cloud distribution. This structural feature makes 1 - (3 - amino) pyridine exhibit unique properties in many chemical reactions. Its amino group is an active check point and can participate in nucleophilic substitution, acylation, alkylation and other reactions. In nucleophilic substitution, the nitrogen atom of the amino group attacks the electrophilic reagent with its lone pair electron, and then generates new compounds.
In terms of stability, the conjugated system of the pyridine ring imparts a certain stability, but the introduction of amino groups will also affect its stability. Amino groups have a power supply effect, which can increase the electron cloud density of the pyridine ring and enhance its activity in reacting with electrophilic reagents, which may slightly weaken the stability. However, under normal conditions, 1- (3-amino) pyridine can maintain a relatively stable state without extreme conditions such as strong electrophilic reagents, strong acids, strong bases, or high temperatures.
For example, in an environment at room temperature and pressure without special reagents, 1- (3-amino) pyridine can be stored for a long time without significant chemical changes. However, if it is in a strong acid environment, the amino group is easily protonated, changing the molecular electron cloud distribution, affecting the stability of the pyridine ring, or initiating other reactions on the ring. For example, at high temperatures and in the presence of oxidants, reactions such as oxidation may also occur, resulting in structural changes and reduced stability.
Overall, 1- (3-amino) pyridine is relatively stable under conventional mild conditions, but under specific chemical environments and reaction conditions, its stability will be affected and corresponding chemical transformations will occur.

The market price of 1 - (3 - amino) pyridine is about how much per catty? This is required by the chemical industry and is related to many industries. I will answer it with an ancient saying.
In today's world, the chemical industry is prosperous. This product is in the market, and its price is not fixed. It often changes over time and varies with quality. However, roughly speaking, its price varies according to purity, supply and demand. If the purity is normal, the price in the market may be between tens of dollars and more than a hundred dollars per catty. If its purity is excellent and suitable for high-end use, the price will jump, and it can reach hundreds of dollars per catty.
3-aminopyridine has a wide range of uses and is important in the pharmaceutical and pesticide industries. In the pharmaceutical system, the raw materials that can be used as medicines are related to the health of people's livelihood; the timing of pesticides can help agricultural products and ensure the abundance of fields and acres. Therefore, its demand is always prosperous, and the price also fluctuates. If the supply and demand of the city are flat, the price will be stable; if the demand exceeds the supply, the price will rise; if the supply exceeds the demand, the price will fall. In addition, the difficulty of production, the level of cost, is also a variable in the price. It is roughly so with its price. If you want to know the exact number, you need to consult the city Jia and watch the changes of the times.
