2-Methylthiopyridine, organic compounds are also. Its physical properties are quite important, let me come to you one by one.
Looking at its appearance, at room temperature, it is mostly colorless to light yellow liquid, like the radiance of morning dew, with a slightly yellowish color, just like the shimmer of the rising sun.
As for its smell, it is really unique. There is a pungent smell of thiol, which smells like being in a place filled with sulfur. This smell is rich and strong and irritating, which is impressive and unforgettable.
The boiling point is between 215 and 217 degrees Celsius. When the temperature gradually rises, 2-methylthiopyridine is like a butterfly of feather, transforming from liquid to gaseous state and beginning to transpire.
Its melting point is about -21 ° C. At lower temperatures, it is like a sleeping crystal, condensing into a solid state and lying at a low temperature.
2-methylthiopyridine has a density of about 1.12 g/cm ³, which is slightly heavier than water. If it is placed in one place with water, it will sink to the bottom like a stone and slowly sink.
In terms of solubility, it is quite compatible with organic solvents, such as ethanol and ether, just like fish get water, and the two blend with each other. However, in water, the solubility is extremely limited, just like the difficulty of oil and water, only a few permits are allowed to disperse in it.
The physical properties of this compound are of great significance in many fields such as chemical industry and medicine. Its unique properties may become the key to developing new drugs, or the cornerstone of a new path for chemical synthesis, which is something that cannot be underestimated.

2-Methylthiopyridine, this material is still stable. In its molecular structure, the pyridine ring is connected to the methylthio group, and this specific structure determines its chemical properties.
In terms of stability, the pyridine ring has aromatic properties. Due to the conjugation system, the energy is reduced, which makes 2-methylthiopyridine less prone to violent reactions such as ring opening under normal conditions. Its aromatic properties make the compound resistant to heat, light and some chemical reagents. However, the nitrogen atom on the pyridine ring has lone pairs of electrons and is weakly basic. When it encounters strong acids, it will react with it to form salts, which does not destroy its main structure, but changes its chemical state.
In addition to methylthio, the sulfur atom is moderately electronegative, and the C-S bond connected to the carbon atom has a certain polarity. Methylthio can undergo some nucleophilic or electrophilic reactions, but compared with many active functional groups, the reaction conditions are usually more severe. For example, at a specific catalyst and a suitable temperature, the sulfur atom of methylthio may participate in the reaction as a nucleophilic check point, but such reactions often require a more severe reaction environment, which also reflects that 2-methylthiopyridine is relatively stable under conventional conditions.
However, the stability of 2-methylthiopyridine will be challenged under high temperatures, strong oxidants or special catalyst environments. Strong oxidants such as potassium permanganate can oxidize methylthiopyridine under specific conditions, changing its structure and properties. At high temperatures, the vibration of some chemical bonds inside the molecule intensifies, which may cause bond breaks and rearrangements, thereby changing its chemical structure and stability. However, in general, 2-methylthiopyridine can maintain a relatively stable state under common laboratory and general industrial environment conditions.

The preparation process of 2-methyl thiopyridine is a crucial link in the field of chemical synthesis. There are various paths to its preparation, and each has its own subtlety.
One is the method of using pyridine as the initial raw material. Pyridine can be introduced into methyl thiopyridine at a suitable temperature and reaction time under the action of specific reagents. In this process, it is necessary to strictly control the reaction conditions, such as high or low temperature, which will affect the purity and yield of the product. If the temperature is too high, it may cause frequent side reactions and generate many impurities; if the temperature is too low, the reaction rate will be slow and take a long time.
Second, other nitrogen-containing heterocyclic compounds are also used as starting materials, and after multi-step reactions, they are skillfully converted into 2-methylthiopyridine. Although this route is complicated, it can effectively avoid some side reactions and improve the quality of the product. Between each step of the reaction, the intermediate product needs to be carefully treated to ensure its stability and reactivity.
Furthermore, catalysts play a pivotal role in the synthesis of 2-methylthiopyridine. A suitable catalyst can significantly reduce the activation energy of the reaction, speed up the reaction process, and enable the reaction to proceed under milder conditions. And different types of catalysts also affect the selectivity of the reaction, or make the reaction more inclined to form the target product and reduce the formation of impurities.
In the actual production process, in addition to focusing on the reaction itself, the subsequent separation and purification steps should not be underestimated. Commonly used methods, such as distillation, extraction, recrystallization, etc., have their own strengths. Distillation can achieve preliminary separation according to the difference in boiling points of different substances; extraction can utilize the different solubility of substances in different solvents to enrich the target product; recrystallization can further improve the purity of the product and obtain high-purity 2-methylthiopyridine.
In summary, the production process of 2-methylthiopyridine requires comprehensive consideration of raw material selection, reaction conditions, catalyst application, separation and purification, etc., in order to achieve high-efficiency and high-quality production goals.

The price of 2-methylthiopyridine in the market is difficult to determine due to various reasons. Factors such as supply and demand trends, the complexity of the process, the abundance of raw materials, and the competition in the market are all involved.
In the past, if the supply and demand were appropriate, the process was easy, and the raw materials were abundant, the price might be relatively easy. However, if the scarcity of raw materials, the complexity of the process, or the surge in demand, the price would rise.
Looking at the market in the past, the price of this substance often fluctuated between tens of yuan and hundreds of yuan per kilogram. If it is in a state of abundant supply and normal demand, its price may fall in a lower range, or tens of yuan per kilogram. However, in the event of a shortage of raw materials or a sharp increase in industry demand, the price may rise to a high of several hundred yuan per kilogram.
Furthermore, the price varies depending on the quality level. High-quality products are often higher than ordinary products due to stricter requirements on craftsmanship and purity. And the amount of purchase also affects the price. For bulk purchases, merchants may give discounts due to large quantities, and the price should be lower than that of retail.
Therefore, in order to know the exact price, the exact number can be obtained by consulting chemical raw material suppliers, traders, or looking at the latest quotations from relevant trading platforms in real time.
