2-% hydrazine-5-methylpyridine is an organic compound with many unique physical properties.
Looking at its properties, under room temperature and pressure, 2-% hydrazine-5-methylpyridine is mostly colorless to light yellow liquid, with clear texture and good light transmittance. Approaching the fine smell, you can feel that it emits a specific smell, which is more recognizable and different from the smell of common organic solvents.
On the melting point, due to the molecular structure and intermolecular forces, the melting point of the substance is relatively low, and it is easy to change from solid to liquid in warm environments. The boiling point is higher, and in order to transform it from a liquid state to a gaseous state, more energy needs to be applied to make the molecule overcome the intermolecular force and escape the liquid phase.
In terms of solubility, 2-% hydrazine-5-methyl pyridine exhibits good organic solvent solubility and can be miscible with common organic solvents such as ethanol, ether, and acetone in any ratio. This property is due to the interaction between its molecular structure and organic solvent molecules, such as hydrogen bonds and van der Waals forces, which promote mutual mixing. However, its solubility in water is limited, because water is a highly polar solvent, while 2-% hydrazine-5-methyl pyridine has a certain polarity, but it is difficult to fully interact with water molecules, making it difficult to dissolve in water.
In terms of density, the density of 2-% hydrazine-5-methylpyridine is greater than that of common light organic solvents, and slightly less than that of water when compared with water. When it is co-placed with water in a container, there will be stratification, with 2-% hydrazine-5-methylpyridine living in the upper layer.
In addition, 2-% hydrazine-5-methylpyridine is relatively stable chemically at room temperature, but under certain conditions, such as high temperature, strong oxidant or strong acid and alkali environment, chemical reactions will occur, showing active chemical activity.

2-%E6%B0%9F-5-%E7%94%B2%E5%9F%BA%E5%90%A1%E8%80%85 is an organic compound with interesting chemical properties and considerable research value.
In this compound, due to its specific atomic connection and electron distribution, it exhibits unique reactivity. In nucleophilic substitution reactions, its performance is particularly prominent. Due to the electron cloud density of specific atoms in its molecular structure, nucleophilic reagents are easy to attack, and then substitution reactions occur. For example, when encountering halogenated hydrocarbons, halogen atoms can be replaced by specific nucleophilic groups to form new organic products.
Furthermore, in redox reactions, 2-%E6%B0%9F-5-%E7%94%B2%E5%9F%BA%E5%90%A1%E8%80%85 can also play an important role. The oxidation state of some atoms in its molecules can be changed due to changes in the external environment, or oxidized or reduced. Under the action of suitable oxidants, specific groups in the molecule can lose electrons, undergo oxidation reactions, and transform into groups with higher oxidation states; conversely, when encountering strong reducing agents, electrons can be obtained, and reduction reactions can occur, thereby changing the chemical structure and properties of the molecule.
In addition, the compound also has a certain response to acid-base environments. Under acidic conditions, some functional groups in the molecule may protonate, causing the distribution of electron clouds to change, which in turn affects the reactivity and chemical properties of the whole molecule; in alkaline environments, deprotonation reactions may occur, triggering a series of different chemical reactions. This property makes 2-%E6%B0%9F-5-%E7%94%B2%E5%9F%BA%E5%90%A1%E8%80%85 have potential applications in organic synthesis and chemical analysis.

To prepare 2-alkyne-5-methylhexane, there are two methods.
First, it can be prepared by the elimination reaction of halogenated hydrocarbons. First, take an appropriate halogenated hydrocarbon, such as 5-methyl-2-bromohexane, and treat it with an ethanol solution of a strong base such as sodium ethyl alcohol. Under the action of a strong base, the bromine atom is removed from the hydrogen atom on the adjacent carbon to form a carbon-carbon double bond. In this process, following the Zaitsev rule, the olefin with more substituents is preferentially formed. Then, the obtained olefin and hydrogen bromide undergo an anti-Martensitic addition reaction in the presence of peroxide to obtain an anti-Martensitic addition product. Finally, the product is co-heated with the alcohol solution of the strong base, and the elimination reaction occurs again, that is, the target product 2-alkyne-5-methylhexane is formed. This method is a little complicated, but each step of the reaction is more classical and has strong controllability.
Second, it can be achieved by the reaction of sodium acetylene and halogenated hydrocarbons. First, acetylene reacts with sodium metal in a suitable solvent such as liquid ammonia to form sodium acetylene. Sodium acetylene has strong nucleophilicity and can undergo nucleophilic substitution with 2-bromo-5-methylhexane. In this reaction, the alkynyl anion of sodium acetylene attacks the alpha-carbon of the halogenated hydrocarbon, and the bromine ion leaves, thus forming a new carbon-carbon bond and directly generating 2-alkynyl-5-methylhexane. This method is relatively simple and has a high yield, which is quite commonly used in organic synthesis. It should be noted that the reaction system should be anhydrous and oxygen-free during the reaction to avoid other side reactions of sodium acetylene and affect the product formation.

Wen Jun inquired about the price range of 2-ene-5-methylheptane in the market. However, the price of this product often changes due to multiple reasons, and it is difficult to determine its fixed number.
First, the quality and quantity of the product affect the price. If the production of fine and sufficient, the supply exceeds the demand, and the price may decrease; conversely, the quality and quantity are small, and the supply is difficult to meet the demand, and the price will increase.
Second, the purchase quantity also has an impact. If you buy in bulk, you may make a profit, and the price is better; if you buy in bulk, the price may be slightly higher.
Third, the supply and demand situation of the market is also the key. If the industry is booming, it needs to increase significantly, and the price may rise; if the industry is sluggish, it needs to decrease significantly, and the price may fall.
Fourth, the cost of transportation and storage is also related to the price. The origin is far from the city, and the cost of transportation and storage is high, and the price will rise; if the fee is low, the price may fall.
According to the common situation of the market, the price of 2-ene-5-methylheptane is between tens and hundreds of dollars per kilogram. However, this is only an approximate number, and the actual price shall be subject to real-time market conditions, buyer demand and the pricing of the merchant. To know the exact price, it is advisable to consult the chemical raw material supplier or similar trading platform to obtain an accurate number.
