In conclusion, 2-amidinopyridine hydrochloride plays an indispensable role in many fields due to its diverse reactivity and unique chemical properties.

The method of preparing 2-amidinopyridine hydrochloride is particularly important. The process of its preparation is often started with pyridine. The pyridine is first reacted with appropriate reagents to introduce the amidine group.
Usually pyridine and cyanyl compounds are used as raw materials and obtained through several steps. If pyridine and cyanohalide are reacted with nucleophilic substitution under suitable conditions, or in the presence of a specific catalyst, the nitrogen atom on the pyridine ring attacks the carbon connected to the halogen atom in the cyanohalide with its lone pair electrons, and the halogen atom leaves to obtain the cyanogroup-containing pyridine derivative. < Br >
Then, the step of hydrolysis and salt formation of the cyanyl-containing pyridine derivative. During hydrolysis, the cyanyl group is converted into a amidine group, and the common acid solution, such as hydrochloric acid, is hydrolyzed at an appropriate temperature and reaction time. After hydrolysis, due to the presence of hydrochloric acid in the system, it naturally forms 2-amidine pyridine hydrochloride.
There may also be other methods, but precise control of the reaction conditions is necessary, such as temperature, reactant ratio, reaction time, etc. Too high or too low temperature can cause the reaction to deviate from expectations, or the reaction rate is too slow, or side reactions are clustered. Improper proportion of reactants will also affect the yield and purity of the product. Only by accurately grasping these various elements can high-purity 2-amidinopyridine hydrochloride be obtained.

2-Amidinopyridine hydrochloride is also a chemical substance. When storing, pay attention to many matters.
The first environment should be placed in a cool place. Because the temperature is too high, or the substance will undergo a chemical reaction, which will damage its quality. And it must be dry and avoid humid places, otherwise after moisture absorption, it may cause changes in its properties or even deterioration.
Furthermore, the packaging must be tight. The substance may react with air components, such as oxygen, carbon dioxide, etc. Tight packaging can prevent its contact and ensure its stability.
And it needs to be kept away from fire and heat sources. This substance may be flammable, near fire or heat, and may cause fire and endanger safety. < Br >
At the same time, it should not be co-stored with oxidizing substances. Oxidizing substances are highly active and can easily cause violent reactions or serious consequences such as explosion when exposed to them.
The storage place should also be well ventilated. Good ventilation can reduce the accumulation of harmful gases, ensure environmental safety, and reduce the possibility of danger due to high gas concentration.
When handling, be sure to handle it with care. 2-amidine pyridine hydrochloride may be fragile, rough handling, damaged packaging, both damaged substances and easy to leak, endangering the environment and people.

The market price range of 2-amidinopyridine hydrochloride is difficult to determine. The price often varies due to many factors, and it is impossible to generalize.
First, it concerns the manufacturer. Different manufacturers have different production processes and cost control. Reputable and well-crafted large factories produce this product, or because of its high quality, the price is high; while emerging small factories compete for the market, or price it slightly lower to attract buyers.
Second, it depends on the purity. If the purity is extremely high and meets the high standards required for scientific research, it can be used in fine experiments, high-end pharmaceuticals and other fields, and its price will be high; if the purity is slightly lower, it is only for general industrial use, and the price will be reduced.
Third, the state of market supply and demand is also the key. When the market demand is strong and the supply is limited, if there is a surge in demand for a specific industry, the supply will exceed the demand, and the price will rise; on the contrary, if the supply exceeds the demand, the manufacturer will sell the inventory or reduce the price.
I also checked the ancient books such as "Tiangong Kaiwu" in the past. Although there is no such chemical price, it is common sense. Today's market is complex and changeable. The price of similar things is affected by factors such as origin, quality, and time demand. It is the same as this 2-amidine pyridine hydrochloride. According to the general market conditions, its price may range from tens of yuan to hundreds of yuan per kilogram, but this is only a rough estimate. The actual price needs to be consulted with various suppliers in detail, depending on the current market conditions.
