Pyridine-3-acetic acid hydrochloride (Pyridine-3-acetic acid HCl) is useful in many fields such as medicine and chemical synthesis.
In the field of medicine, it is often a key intermediate in drug synthesis. The structures of both gainpyridine and acetic acid have unique chemical activities, which can be connected to the molecular structure of drugs through chemical reactions, giving drugs specific pharmacological activities and pharmacokinetic properties. For example, in the preparation of some antibacterial drugs, pyridine-3-acetic acid hydrochloride is involved, which may optimize the affinity of drugs to specific bacterial targets and improve antibacterial efficacy. Or in the research and development of neurological drugs, the modified pyridine-3-acetate hydrochloride fragment can be added, which can change the ability of the drug to pass through the blood-brain barrier and enhance the therapeutic effect on brain diseases.
In the field of chemical synthesis, this compound is also widely used. First, it can be used as a starting material for organic synthesis, and many complex organic compounds can be derived through a series of chemical reactions. Second, because of its special structure and acidity, it can be used as a catalyst to accelerate the reaction process and improve the reaction selectivity in some organic reactions. For example, in common organic reactions such as esterification and condensation reactions, pyridine-3-acetic acid hydrochloride may exhibit unique catalytic properties, promoting the reaction to proceed more efficiently, providing a more convenient and efficient way for chemical production, and assisting in the synthesis and preparation of new materials and fine chemicals.

The method for preparing pyridine-3-acetic acid HCl is described below.
First, pyridine-3-acetic acid is taken as the starting material. This compound can be prepared by a specific reaction of the corresponding pyridine derivative, for example, with 3-methylpyridine as the starting material, and through oxidation reaction, the methyl group is converted to a carboxyl group to obtain pyridine-3-acetic acid.
After pyridine-3-acetic acid is obtained, it is dissolved in a suitable solvent, such as anhydrous ethanol, dichloromethane, etc. This solvent needs to be able to dissolve pyridine-3-acetic acid well and not interfere with the subsequent reaction.
Then, slowly introduce dry hydrogen chloride gas into it. When introducing hydrogen chloride gas, pay attention to the condition of the reaction system, control the ventilation speed, and do not be too fast to avoid too violent reaction. The reaction process can be controlled by observing the phenomenon of the solution, such as whether there is precipitation formation and temperature changes.
Hydrogen chloride reacts with pyridine-3-acetic acid. The nitrogen atom on the pyridine ring has a lone pair electron, which can combine with the hydrogen ion in hydrogen chloride to form pyridine-3-acetic acid hydrochloride.
After the reaction is completed, the reaction mixture is processed. If the boiling point of the solvent used is low, the solvent can be removed by reduced pressure distillation. If the product is precipitated in solid form, it can be collected by filtration, and then washed with an appropriate amount of cold solvent to remove impurities. If the product is in a solution state, a bad solvent can be added to promote the crystallization and precipitation of the product. After filtration and drying, pure pyridine-3-acetic acid hydrochloride can be obtained. During the whole preparation process, attention should be paid to the control of reaction conditions, such as temperature, reaction time, proportion of reactants, etc., to ensure the purity and yield of the product.

I think what you are asking is about the market price of pyridine-3-acetic acid hydrochloride. However, the market price often changes with many factors, such as raw material supply, production process, market demand, regional differences, etc. It is difficult to have an exact constant price.
In the past, the price of chemical products may fluctuate due to the abundance of raw materials. If the raw material of pyridine-3-acetic acid hydrochloride is easy to obtain and the supply is sufficient, its price may stabilize or even decline; conversely, if the raw material is scarce and the supply is tight, the price will rise.
The quality of the production process also affects the price. Advanced technology may improve production efficiency, reduce costs, and make products more price competitive in the market; while backward technology, the cost remains high, and the product price is difficult to reach the people.
Market demand is even more critical. If there is a large increase in demand for pyridine-3-acetate hydrochloride at a certain time, and the supply is in short supply, merchants will raise prices in pursuit of profit; if the demand is low and the supply exceeds the demand, they may sell at a reduced price for promotion.
As for regional differences, different places have different prices due to different transportation costs and local economic conditions. In prosperous places, the demand is large and the transportation is convenient, or the price is slightly higher; in remote places, the demand is small and the transportation is inconvenient, and the price may be relatively low. Therefore, in order to know the exact market price of pyridine-3-acetic acid hydrochloride, we can obtain a more accurate price by inquiring the chemical product trading platform in real time, consulting relevant suppliers, or referring to industry reports.

Pyridine-3-acetic acid hydrochloride is a chemical substance, and its storage conditions are crucial to the stability and quality of the substance. This substance should be stored in a cool, dry and well-ventilated place.
A cool place can prevent it from decomposing or deteriorating due to excessive temperature. If the temperature is high, the chemical reaction rate may be accelerated, the molecular activity may be enhanced, or the structure of the substance may be changed, which affects its chemical properties.
A dry place can be protected from moisture. Pyridine-3-acetic acid hydrochloride may be hygroscopic. After hygroscopic, it may dissolve, agglomerate, or chemically react with water, damaging its original characteristics.
Well-ventilated can ensure the air circulation in the storage environment, disperse harmful gases that may evaporate in time, avoid potential safety hazards caused by gas accumulation, and maintain fresh ambient air, which is beneficial for material storage.
Furthermore, it should be stored separately from oxidants, acids, alkalis, etc., because of its active chemical properties, contact with these substances or react violently, endangering safety. The storage place should also be kept away from fire and heat sources to prevent open flames to prevent fire or explosion accidents.
When storing, the container must be tightly sealed to prevent leakage. After taking it, it should be sealed in time to maintain good sealing to ensure stable material quality and protection from external environmental interference. In this way, pyridine-3-acetic acid hydrochloride can be properly preserved to maintain its chemical properties and efficiency.
