3-Pyridyl ethanol is an organic compound. It has unique physical properties, which are described in detail by you.
Looking at its properties, under normal temperature and pressure, 3-pyridyl ethanol is a colorless to light yellow liquid, with a clear and translucent appearance, like a clear spring, without the slightest turbidity. Its smell has a slight special smell, not pungent and intolerable, but also different from the ordinary fragrance, with a unique indescribable smell.
When it comes to boiling point, the boiling point of this compound is quite high, about 270 ° C. The boiling point is the critical temperature at which the substance changes from liquid to gaseous state. Such a high boiling point indicates that the intermolecular force is strong, and more energy is required to vaporize it.
As for the melting point, 3-pyridyl ethanol has a lower melting point, about -20 ° C. Low melting point means that it can be in a liquid state at a relatively low temperature. This property allows it to maintain good fluidity in some low-temperature environments or related process operations, which is conducive to various reactions or operations.
Its solubility is also worthy of attention. 3-pyridyl ethanol can be miscible with water in any ratio, because its molecular structure contains polar groups, which can form hydrogen bonds and other interactions with water molecules, so it can be closely fused. At the same time, it also exhibits good solubility in most organic solvents, such as ethanol, ether, etc. This property makes it an excellent solvent or reaction medium in organic synthesis and various chemical experiments, and helps the smooth development of many chemical reactions.
In addition, the density of 3-pyridyl ethanol is slightly higher than that of water, about 1.112 g/cm ³. The density characteristic is of great significance in separation, extraction and other operations. According to the differences, the experimental process can be skillfully designed to achieve effective separation from other substances.
In summary, the various physical properties of 3-pyridyl ethanol make it have a wide range of application prospects in many fields such as chemical industry and medicine.

3-Pyridyl ethanol has unique chemical properties and is very interesting. At room temperature, this substance is mostly colorless to light yellow liquid, with a certain degree of volatility, its taste is specific, and slightly irritating.
When it comes to solubility, 3-pyridyl ethanol is soluble in water and can be miscible with many organic solvents such as ethanol and ether. This property makes it play a key role in many chemical reactions and industrial processes.
Its chemical activity is also worth exploring. The existence of the pyridine ring gives it weak alkalinity and can react with acids to form corresponding salts. And the electron cloud distribution on the pyridine ring is special, which makes it prone to electrophilic substitution reaction. It is common to introduce various functional groups at specific positions on the ring, and then derive a variety of derivatives, which are widely used in the field of organic synthesis.
And its ethanol side chain part also has the typical properties of alcohols. It can undergo esterification reaction, and form ester compounds with organic acids under the action of catalysts; when it encounters strong oxidants, it can also be oxidized to form corresponding formaldehyde or carboxylic acids and other products.
3-pyridine ethanol has rich chemical properties, providing a broad application space for many fields such as organic synthesis and drug research and development. It is an indispensable and important compound in chemical research and industrial production.

For 3-pyridyl ethanol, there are several ways to prepare it. One method can start from 3-cyanopyridine. First, 3-cyanopyridine reacts with metal hydrides such as lithium aluminum hydride in a suitable organic solvent at low temperature and under stirring. Lithium aluminum hydride has strong reductive properties, and cyano (-CN) can be reduced to -CH ² NH ², but the reaction is violent, and the temperature needs to be carefully controlled. Then, after acidification treatment, -CH -2 NH -2 is converted to -CH -2 NH 🥰, and then neutralized with a base to obtain 3-pyridyl ethanol.
Another method uses 3-pyridyl formaldehyde as a raw material. The 3-pyridyl formaldehyde is reacted with Grignard's reagent, and the hydrocarbyl part of the Grignard's reagent nucleophilically attacks the carbonyl carbon of the aldehyde group to form a new carbon-carbon bond. After the reaction is completed, the hydrolysis step can generate alcohol hydroxyl groups to obtain 3-pyridyl ethanol. In this process, the preparation and use of Grignard's reagent requires an anhydrous and oxygen-free environment to prevent its failure.
Furthermore, 3-methylpyridine can be obtained by oxidation and reduction in two steps. First, the methyl group of 3-methylpyridine is oxidized to a carboxyl group with a suitable oxidizing agent, such as potassium permanganate or potassium dichromate, to obtain 3-pyridyl carboxylic acid. After a strong reducing agent, such as sodium borohydride and Lewis acid synergistically, or under the condition of catalytic hydrogenation, the carboxyl group is reduced to hydroxymethyl to obtain 3-pyridyl ethanol. In this way, the oxidation step needs to pay attention to control the reaction conditions to avoid excessive oxidation.
Although there are many methods for preparing 3-pyridyl ethanol, each method has its advantages and disadvantages. Experimenters should choose the appropriate one according to actual needs and conditions.

3-Pyridyl ethanol is an organic compound, and there are many points to be paid attention to during use.
First, safety protection must be comprehensive. This compound may have certain toxicity and irritation, and appropriate protective equipment should be worn when contacting, such as gloves, goggles and laboratory clothes, to prevent it from contacting the skin and eyes. If you come into contact accidentally, you should rinse it with plenty of water immediately. If the situation is serious, you must seek medical attention in time.
Second, storage conditions are very critical. It should be stored in a cool, dry and well-ventilated place, away from fire sources and oxidants. Because of its flammability, in case of open flames, hot topics or ignition, proper storage can avoid fire and explosion hazards.
Third, the use and operation should be cautious. Carry out relevant operations in the fume hood to ensure air circulation and avoid inhaling its volatile gases. Accurately control the dosage, according to the experimental or production needs, use precise measuring tools to measure, to prevent experimental deviations or production accidents due to improper dosage.
Fourth, waste disposal should be in compliance. Waste after use must not be discarded at will, and must be properly disposed of in accordance with relevant regulations. Generally speaking, it should be collected centrally and handed over to professional institutions for harmless disposal to avoid pollution to the environment. In conclusion, when using 3-pyridyl ethanol, all aspects of protection, storage, operation, and waste disposal must be strictly controlled to ensure that personnel safety and the environment are not damaged, and related work can be carried out smoothly.
