3-Hydroxy-2-methylpyridine is an organic compound with unique physical properties. Looking at its appearance, under room temperature and pressure, it is mostly colorless to light yellow liquid, clear and transparent, just like the pure Liquan, without suspended impurities, showing a clear state.
When it comes to smell, it exudes a special smell, neither a fragrant fragrance nor a pungent and intolerable smell, but a unique smell of organic compounds. At first glance, it is impressive. Its melting point is in a relatively low range, about -15 ° C, like thin ice that is easy to melt in cold winter. This property allows it to maintain a liquid shape in a lower temperature environment. The boiling point is between 220 and 222 degrees Celsius, just like the boiling point of water as its unique sign, requiring a higher temperature to make it boil into a gaseous state.
In addition, 3-hydroxy-2-methyl pyridine also has characteristics in terms of solubility. It is soluble in many common organic solvents, such as ethanol, ether, etc., just like fish entering water, it naturally fuses. This is because it has specific interactions with these organic solvent molecules and is compatible with each other. However, its solubility in water is relatively limited, only slightly soluble, just like in water, it can only be dispersed slightly, and it is difficult to completely blend.
As for the density, it is about 1.16 g/cm ³, which is slightly higher than the density of water, so if it is placed in the same place as water, it will slowly settle on the bottom of the water, like a heavy object. In addition, the compound has a certain degree of hygroscopicity, just like a dry sponge, in a high humidity environment, it will absorb moisture in the air, thus affecting its own purity and physical state.

To prepare 3-amino-2-methylpyridine, there are various methods. One is to start with 2-methylpyridine, nitrate to obtain 3-nitro-2-methylpyridine, and then reduce the nitro group to amino group by means of iron powder, hydrochloric acid or hydrogen, and catalyst. This method is common and convenient.
Or it can be prepared by suitable organic compounds containing nitrogen and methyl groups through a series of reactions such as condensation and cyclization. First, the nitrogen-containing reagent is condensed with methyl-containing ketenes or alkenaldes, and then cyclized to form a pyridine ring. Substituents on the ring may need to be modified later to obtain the target product.
There are also pyridine derivatives as raw materials, through a specific position substitution reaction. Select a pyridine derivative with a suitable substituent, use a nucleophilic substitution or an electrophilic substitution reaction, under appropriate conditions, introduce an amino group and a methyl group at a designated position, and convert it through a multi-step reaction to obtain 3-amino-2-methylpyridine. When preparing
, it is necessary to pay attention to the control of reaction conditions, such as temperature, pressure, catalyst type and dosage, which have a significant impact on the yield and selectivity of the reaction. And the separation and purification after each step of the reaction are also critical, which is related to the purity and quality of the product.

When storing and transporting 3-amino-2-methylpyridine, many matters need to be paid attention to.
When storing, the first choice of environment. It should be placed in a cool and ventilated place, away from fire and heat sources. Because of its certain chemical activity, high temperature or open flame is easy to cause danger. The temperature of the warehouse should be controlled within an appropriate range to prevent the change of material properties. And it needs to be stored separately from oxidizing agents and acids, and must not be mixed. Because this substance encounters oxidizing agents and acids, or has a violent chemical reaction, it endangers safety. At the same time, the storage area should be equipped with suitable materials for containing leaks. Once there is a leak, it can be dealt with in time to reduce the harm.
During transportation, the packaging must be tight and stable. Appropriate packaging materials should be selected in accordance with relevant regulations to ensure that the packaging is not damaged or leaked during transportation. Transportation vehicles must also meet safety standards and be equipped with corresponding fire equipment and leakage emergency treatment equipment. During transportation, the route should be carefully planned to avoid sensitive areas such as densely populated areas and water sources. And transportation personnel must be professionally trained to be familiar with the dangerous characteristics and emergency treatment methods of 3-amino-2-methylpyridine. During transportation, various regulations of the transportation department should be strictly followed, and no overloading or speeding should be allowed to ensure the safety of the whole transportation process. In this way, the risk can be minimized during the storage and transportation of 3-amino-2-methylpyridine, ensuring the safety of personnel and the environment.
