The synthesis of (R) -2- (1-hydroxyethyl) pyridine is an important research in the field of chemistry. To obtain this compound, there are many common paths.
One of them can be initiated by pyridine derivatives. Using specific pyridine compounds as raw materials, the structure containing hydroxyethyl is constructed by introducing appropriate substituents. If a suitable pyridine halogen is selected, a nucleophilic substitution reaction is used to attack the halogen atom with a hydroxyl-containing nucleophilic reagent, and then hydroxyethyl is introduced. This process requires careful selection of reaction conditions, such as temperature, solvent, type and dosage of base, etc. If the temperature is too high or too low, it may affect the reaction rate and product selectivity; the polarity and solubility of the solvent also have a significant effect on the reaction process; the strength and dosage of the base are related to the activity of the nucleophilic reagent.
Second, the synthesis is guided by chiral auxiliaries. Chiral auxiliaries can guide the formation of products with specific configurations in the reaction, which is especially critical for the acquisition of (R) -2- (1-hydroxyethyl) pyridine compounds with specific chiral properties. First, the chiral auxiliaries are combined with pyridine derivatives. During the reaction, the steric resistance and electronic effects of the chiral auxiliaries can guide the reaction towards the direction of generating the target chiral configuration. After the reaction is completed, the chiral adjuvant can be removed through appropriate steps to obtain the target product. This method requires careful design of the structure and reaction process of the chiral adjuvant to ensure the high efficiency of chiral induction and the purity of the product.
Third, the biocatalytic synthesis method is also feasible. Some enzymes have high stereoselectivity and can catalyze specific substrates to produce products of specific configurations. Enzymes with relevant catalytic activities can be screened, and (R) -2 - (1-hydroxyethyl) pyridine can be synthesized by enzyme-catalyzed reaction with suitable substrates. This method is green and environmentally friendly, and the conditions are mild. However, it is necessary to find an efficient enzyme source and optimize the enzyme-catalyzed reaction conditions, such as pH value, temperature, substrate concentration, etc., in order to improve the reaction efficiency and product yield.

(R) -2- (1-hydroxyethyl) pyridine, this is an organic compound with unique physical properties. Its appearance is often colorless to light yellow liquid, and it is quite stable at room temperature and pressure.
Its solubility is partially soluble in water, because the hydroxyl group in the molecule can form hydrogen bonds with water molecules, which enhances the affinity of the two. However, the existence of the pyridine ring limits its solubility in water, resulting in only partial miscibility.
When it comes to the boiling point, it is about a certain temperature range, which is due to the force between molecules. In addition to the van der Waals force between molecules, the hydrogen bonding caused by the hydroxyl group makes the intermolecular binding more tightly. To make it boil, more energy needs to be input to overcome this force, so the boiling point is at a corresponding value.
As for the melting point, it is also a specific temperature. The molecular arrangement regularity of the compound and the intermolecular forces together determine the melting point. When the temperature reaches the melting point, the molecule obtains enough energy to break free from the lattice and convert from solid to liquid.
In addition, (R) -2- (1-hydroxyethyl) pyridine has a certain density, which is one of its important physical properties. Density reflects the mass per unit volume of a substance and is related to the molecular structure and the degree of intermolecular packing. Due to the specific structure and composition of the molecule, it has a corresponding density value.
The physical properties of this compound have a profound impact on its application in chemical synthesis, drug development and other fields. In chemical synthesis, properties such as solubility and boiling point are related to the choice of reaction conditions and product separation; in drug development, physical properties are closely related to drug absorption, distribution, metabolism and other processes, so it is crucial to understand its physical properties.

(R) - 2 - (1 - hydroxyethyl) pyridine, this is an organic compound. It has many unique chemical properties.
First of all, its physical properties, at room temperature, or in a liquid state, with a specific odor, in organic solvents, such as ethanol, ether, etc., have a certain solubility. This solubility is derived from its molecular structure, both the aromatic structure of the pyridine ring and the polar group containing hydroxyethyl, which allows it to interact with polar and partial non-polar organic solvents.
Furthermore, on its chemical activity. Pyridine ring is an electron-rich aromatic system with nucleophilic properties. In many reactions, the nitrogen atom of the pyridine ring can be used as a nucleophilic check point to react with electrophilic reagents. For example, in the case of halogenated hydrocarbons, nitrogen atoms can attack the carbon atoms of halogenated hydrocarbons to form quaternary ammonium salts. And its hydroxyethyl group, the hydroxyl group has an active hydrogen atom, which can participate in the esterification reaction. When it encounters carboxylic acids, under acid-catalyzed conditions, the hydroxyl group dehydrates and condensates with the carboxyl group to form corresponding esters. At the same time, because the carbon atom connected to the hydroxyl group is chiral carbon, this chiral structure endows the compound with unique optical activity and has potential application value in the field of asymmetric synthesis.
In addition, the chemical properties of (R) -2- (1-hydroxyethyl) pyridine make it stand out in the fields of drug synthesis and materials science.

Today there is (R) -2- (1-hydroxyethyl) pyridine, and I would like to know its price range in the market. However, I have searched all over the classics, but I have not been able to obtain the exact number. Due to changes in the market, prices often vary according to time, place, quality and supply and demand.
In the past, the prices of the items contained in Tiangong Kaiwu changed with the world. The same is true for this (R) -2- (1-hydroxyethyl) pyridine, or in Dayi, Kyoto, due to the concentration of merchants and the circulation of goods, the price may be different; in remote places, due to difficult transshipment, the price is also different.
And its quality is also the key to the price. If the quality is pure and flawless, the price must be high; if it contains flaws, the price should be low. And in the state of supply and demand, if there is a need for prosperity and a lack of supply, the price will increase; if there is an oversupply, the price will be depressed.
Although the exact price has not been obtained, if you want to know the details, you can visit various pharmaceutical shops, chemical shops, or consult various merchants and experts.
