(S) -2 - (1-hydroxyethyl) pyridine, the physical properties of this substance are quite important, and it is related to its application in many fields.
Its characteristics are often colorless to light yellow liquid, with a clear appearance. Looking at its color, it is like a clear spring, slightly yellowish, like the shimmer of the first light of morning, without turbidity, and it is pure.
When it comes to boiling point, it is about a certain temperature range. The characteristics of this boiling point make it possible to transform from liquid to gaseous state at a specific temperature, just like the boiling of water and turn it into steam. Such characteristics are promising in separation, purification and other processes.
Furthermore, its melting point also has a specific value. When the temperature drops below the melting point, (S) -2- (1-hydroxyethyl) pyridine will solidify from a liquid state to a solid state, just like water freezes into ice when cooled, and the shape changes. This is the key temperature point for the transformation of the state of matter.
In terms of density, there is a fixed value. This value indicates that the mass of this substance per unit volume is like a measure of the weight of an object. In chemical production, it is of great significance for the proportion and measurement of materials.
Solubility is also one of the important physical properties. (S) -2- (1-hydroxyethyl) pyridine may be soluble, slightly soluble, or insoluble in specific solvents. For example, in some organic solvents, it can blend with them, just like salt dissolves in water, forming a uniform mixed system. This property has a great impact on the selection of reaction media and product separation.
Its refractive index also has corresponding values. When light passes through (S) -2- (1-hydroxyethyl) pyridine, it will refract, and the refractive index accurately describes the degree of bending of this light. In the field of analysis and detection, this property can be used to identify and analyze this substance.

In order to obtain (S) -2- (1-hydroxyethyl) pyridine, there are various methods of chemical synthesis. One common method is to start with pyridine and make it condensate with acetaldehyde under the action of a specific catalyst. During this process, the temperature, pressure and time of the reaction are carefully controlled, and the type and dosage of the catalyst also need to be considered. If the cap temperature is too high or too low, it may affect the rate of reaction and the purity of the product; if the pressure is not good, it may cause the reaction to deviate from expectations; and if the amount of catalyst is too much or too little, it also affects whether the reaction can proceed smoothly and the yield of the product.
Second, it can be synthesized by the corresponding halogenated pyridine and hydroxyethyl-containing reagents according to the mechanism of nucleophilic substitution reaction. In this way, suitable solvents and bases need to be selected to promote the occurrence of the reaction. The polarity of the solvent and the strength of the base are all closely related to the process of the reaction. Polar solvents may accelerate the activity of nucleophilic reagents, and the choice of strong bases or weak bases also varies depending on the characteristics of the reactants.
Furthermore, biosynthesis may be used. Using specific microorganisms or enzymes as mediators, using their specific catalytic functions on substrates, to achieve the generation of target products. Although this method is green and environmentally friendly, it is necessary to study the culture conditions of microorganisms and the maintenance of enzyme activity in detail. Such as the composition of the medium, the temperature and pH of the culture, are all key factors. A slight error may affect the growth of microorganisms and the activity of enzymes, and then affect the synthesis of products.

(S) - 2 - (1 - hydroxyethyl) pyridine is a very important organic compound. When storing and transporting, many key matters need to be paid attention to.
First pay attention to environmental conditions. When storing, it should be placed in a cool, dry and well-ventilated place. Because it may be quite sensitive to humidity, it is easy to deteriorate in a humid environment. If moisture absorption and moisture are affected, its chemical properties and purity may be adversely affected, and then the subsequent use effect will be adversely affected.
This is related to temperature control. Avoid high temperature environments, high temperature may cause chemical reactions or even cause them to decompose. In general, the storage temperature should be maintained within a certain range to prevent the stability of the compound from being damaged due to excessive temperature.
Furthermore, during transportation, it is necessary to ensure that the packaging is intact. The packaging of the compound needs to be well sealed to prevent leakage. Once leakage occurs, it will not only cause material loss, but also pose a threat to the transportation environment and the safety of surrounding personnel.
In addition, it is also necessary to pay attention to its compatibility with other substances. When storing and transporting, do not place it with substances that may react with it. Otherwise, it may cause uncontrollable chemical reactions and lead to safety accidents.
In conclusion, the storage and transportation of (S) -2- (1-hydroxyethyl) pyridine requires careful treatment of environmental conditions, packaging conditions, and material compatibility to ensure its quality and safety.

The price of (S) -2- (1-hydroxyethyl) pyridine in the market is difficult to determine. There are three reasons for this: First, the method of preparation of this substance varies, and the difference between raw materials and technology results in different costs and fluctuating prices. If it is made by a fine and complicated method with excellent materials, its price will be high; if it is made by a simple method, the materials used are ordinary, and the price will be slightly lower. Second, the supply and demand of the market are the cardinal of the price. If there are many people in need, if there is a lack of supply, the price will be raised; if the supply exceeds the demand, the price will drop. For example, in a certain field at a certain time, the pharmaceutical and chemical industries are prosperous, and the demand for this material surges, and the producer does not catch up, and the price rises; on the contrary, if the industry is sluggish, the demand decreases sharply, and the price decreases automatically. Third, the situation of the world also has an impact. Changes in the origin and output of raw materials, or blockages in transportation routes, all make costs fluctuate, and the price follows.
Watching the past market conditions, the price of (S) -2- (1-hydroxyethyl) pyridine often fluctuates between tens to hundreds of gold per kilogram. However, this is only an approximation, and with the migration of years, the market situation changes, and it is difficult to determine. If you want to know the real-time price, you must consult the merchant of chemical materials, the market, or the platform for industry news and transactions, in order to obtain a more accurate price.
