2-Bromo-5-cyano-6-methylpyridine

2-Bromo-5-cyano-6-methylpyridine, this is an organic compound. Its chemical properties are unique and interesting.
From the perspective of halopyridine, the bromine atom is endowed with active reaction characteristics. In the nucleophilic substitution reaction, the bromine atom is like a smart target, which is easily attacked by nucleophilic reagents. For example, when encountering hydroxyl negative ions, substitution can occur, the bromine atom leaves, and the hydroxyl group is connected to form a hydroxyl-containing pyridine derivative. This reaction is like a delicate "atom transposition dance".
The presence of cyanide adds a different chemical flavor to the compound. Cyanyl groups have strong electron-absorbing properties, which can affect the electron cloud distribution of the pyridine ring, reduce the density of the electron cloud on the ring, and make the electrophilic substitution reaction on the ring more difficult, just like building an "electronic defense line" around the ring. However, cyanyl groups themselves can participate in many reactions, such as hydrolysis, which can be converted into carboxyl groups, which is like a "chemical transformation show" to generate pyridine compounds containing carboxyl groups. The addition of methyl groups also has its effect. Methyl groups as the power supply group can increase the electron cloud density of the pyridine ring, which has a subtle effect on the reaction activity on the ring. In some reactions, methyl groups can affect the reaction process and product selectivity through the steric hindrance effect, as if occupying a certain space on the reaction stage and controlling the "performance" of other atoms or groups.
Overall, the chemical properties of 2-bromo-5-cyano-6-methyl pyridine are co-shaped by bromine atoms, cyano groups and methyl groups. In the field of organic synthesis, such as the construction of complex pyridine derivative structures, there is unlimited potential, like a "magic key" that opens many doors to the treasure house of organic synthesis.

2-Bromo-5-cyano-6-methylpyridine is also an organic compound. During storage and transportation, many matters need to be paid attention to.
First words storage. This compound should be placed in a cool, dry and well-ventilated place. Because it is more sensitive to heat, high temperature, or cause decomposition, which affects its quality, it should be kept away from heat sources and open flames. And because it may have certain chemical activity, it needs to be stored separately from oxidizing agents, acids, bases and other substances to prevent chemical reactions. The place of storage should be clearly marked with its name, properties and precautions for easy access and management.
Times and transportation. When transporting, it is necessary to ensure that the packaging is intact. Packaging materials should have good sealing and corrosion resistance to effectively prevent compound leakage. Transportation vehicles should also be clean and dry to avoid mixing with other substances that may react with them. During transportation, temperature and humidity should be strictly controlled to avoid violent vibration and collision to prevent package damage and compound leakage. If a leak occurs during transportation, emergency measures should be taken immediately to evacuate the surrounding people to avoid contact with the leak, and appropriate methods should be selected for cleaning and disposal according to the nature of the compound.
In conclusion, during the storage and transportation of 2-bromo-5-cyano-6-methylpyridine, it is necessary to exercise caution and strictly follow relevant norms and requirements to ensure its safety and quality.

2-Bromo-5-cyano-6-methylpyridine, this is an organic compound. Its market price range often fluctuates due to multiple factors.
First, the production scale is related to the price. If large-scale industrial production, by virtue of the scale effect, the unit production cost may be reduced, and the price may be relatively close to the people. However, small-scale production, high cost, and high price will naturally be high.
Second, purity has a significant impact on price. High purity, difficult to prepare, complex process, widely used in medicine, electronics and other fields with strict purity requirements, and the price is often expensive. Low purity, mostly used in general chemical synthesis, the price is relatively low.
Third, the market supply and demand relationship affects the price. When demand is strong and supply is insufficient, the price will rise; if there is excess supply and demand is weak, the price will easily fall.
Fourth, the price of raw materials is also the key. If the price of raw materials for preparing 2-bromo-5-cyano-6-methyl pyridine fluctuates, the cost and price of the product will also change accordingly.
Generally speaking, the price may range from tens to hundreds of yuan per gram. In certain high-purity, small-batch customization scenarios, the price may be higher. However, market conditions are constantly changing, making it difficult to precisely define the specific price range. Practitioners need to pay attention to market dynamics in real time in order to grasp price trends.
