The synthesis method of 2% 2C4-dibromo-3-methyl pentane can follow the following routes:
First, pentane is used as the starting material. First, pentane undergoes a radical substitution reaction with bromine under light conditions. During this process, the hydrogen atoms in the pentane molecule are gradually replaced by bromine atoms to form a mixture of various bromopentane isomers. Then, the product is separated by fractionation and other means to obtain 3-bromopentane. Subsequently, 3-bromopentane reacts with methylating reagents such as methyl lithium (CH 🥰 Li) or Grignard reagents (such as CH 🥰 MgBr). Taking the reaction with methyl lithium as an example, the bromine atom in 3-bromopentane will be replaced by the methyl in methyl lithium to generate 3-methylpentane. After that, 3-methylpentane is subjected to free radical substitution reaction with bromine under specific conditions, such as in the presence of appropriate catalysts (such as benzoyl peroxide, etc.). Due to the selectivity of the reaction, bromine atoms will be introduced at different positions. After careful separation and purification, 2% 2C4-dibromo-3-methylpentane can be obtained.
Second, suitable olefins can be selected as raw materials. For example, take 3-methyl-1-pentene as the starting material. First, 3-methyl-1-pentene is added to hydrogen bromide (HBr). According to the Markov rule, hydrogen atoms are added to the double-bonded carbon atoms with more hydrogen, and bromine atoms are added to the double-bonded carbon atoms with less hydrogen, resulting in 2-bromo-3-methylpentane. After that, 2-bromo-3-methylpentane is reacted with bromine under light or other conditions that initiate free radical reaction, and a second bromine atom is further introduced at a suitable position to generate 2% 2C4-dibromo-3-methylpentane. The purified product can be obtained after separation and purification.
Third, start from alcohols. For example, 3-methyl-3-pentanol is used as a starting material and reacts with hydrobromic acid (HBr) first. The hydroxyl group of the alcohol will be replaced by bromine atoms to generate 3-bromo-3-methylpentane. After that, 3-bromo-3-methylpentane undergoes elimination reaction under the action of strong bases (such as sodium ethanol, etc.) to generate 3-methyl-2-pentene. 3-methyl-2-pentene is then added to bromine to generate 2% 2C3-dibromo-3-methylpentane, which can be converted into 2% 2C4-dibromo-3-methylpentane through some rearrangement reactions or further substitution reactions, and finally separated and purified to meet the purity requirements of the desired product.

2% 2C4-dibromo-3-methylpentane is also an organic compound. Its physical properties are numerous.
Under normal temperature and pressure, it is usually a liquid state. Due to the intermolecular force, the number of carbon atoms and the structural characteristics make it in the liquid state. Its color is mostly colorless and transparent. Those who are pure rarely see variegated colors, and the view is clear.
As for the smell, it often has a special organic smell, but it is not strong and pungent, but milder. However, if you smell it for a long time, you will also feel uncomfortable. Its boiling point has a fixed number, because the molecular structure contains branched chains, compared with linear alkanes, the boiling point is slightly lower, about a specific temperature range, and the cover is the reason for the weakening of the intermolecular force. The melting point also has its value, which is affected by the regularity of molecular arrangement and the force, and is in the corresponding low temperature range.
Furthermore, its density is smaller than that of water. If it is co-placed with water, it will float on water, which is determined by its molecular mass and structure. In terms of solubility, it is extremely insoluble in water, because it is a non-polar organic substance, and water is a polar solvent. According to the principle of "similar miscibility", the two are insoluble. However, organic solvents such as ether, chloroform, etc. are quite soluble. Organic solvents are mostly non-polar or weakly polar, and are similar in structure to 2% 2C4-dibromo-3-methylpentane, so they are very soluble.
The physical properties of 2% 2C4-dibromo-3-methylpentane are probably the same.

I look at the world's prices, which are changing rapidly, but the market price of 2,4-dibromo-3-methylfuran needs to be studied in many ways. At present, the market change is related to the business plan of the merchants, the number of colonies, the balance of supply and demand, and many factors can affect the price.
The business of a merchant is profit-oriented. If the profit of this product is quite abundant, the merchants compete, or cause its production and supply to surge, the price will also drop; on the contrary, if the profit is meager, the business is small, and the goods are thin, the price will be high. And the raw materials for this product are also the main reasons for their abundance and regret. If the raw materials are easy to obtain and inexpensive, the cost of making 2,4-dibromo-3-methylfuran is light, and its price is flat; if the raw materials are rare and the price is high, the cost is heavy, and the price must rise.
Furthermore, the needs of the world are also the cardinal of prices. If there are many people who use 2,4-dibromo-3-methylfuran in the world, the demand is too high, and although the price is high, people are competing to buy it, and the price will rise; if there are few users, the supply will exceed the demand. In order to sell their goods quickly, merchants will reduce their prices to attract customers.
In addition, changes in the situation and decrees also have a great impact on prices. Or there may be heavy taxes imposed by the government, causing the cost of this product to increase sharply and the merchant has to raise the price to protect his profit; or there may be a government order to promote production, causing the output of this product to increase greatly and the price to fall accordingly.
However, I have not been involved in the business sea, and I have not known the situation of the market change. It is difficult to determine the market price of 2,4-dibromo-3-methylfuran. If you want to know the details, you must ask the people in the cities and the experts in the colonization. They are among them and are familiar with the market.

2% 2C4-dibromo-3-methylpentane is an organic compound. During storage and transportation, many matters must be paid attention to:
First, because of its certain chemical activity, the packaging material requirements are quite high. It needs to be stored in a well-sealed container to prevent leakage. If the cover is exposed to air or in contact with oxygen, moisture and other substances, it may cause chemical reactions, cause deterioration, and leakage may endanger the environment and personnel safety.
Second, storage temperature and environment are crucial. It should be placed in a cool, dry and well-ventilated place, away from fire and heat sources. High temperature environment may affect the stability of the compound, and even cause dangerous reactions, such as combustion, explosion, etc.
Third, the relevant regulations and standards must be strictly followed during transportation. Transportation vehicles should be equipped with necessary emergency treatment equipment and protective equipment to prevent accidents during transportation and can respond properly in a timely manner. Transportation personnel must also undergo professional training and be familiar with the characteristics of the compound and emergency treatment methods.
Fourth, in view of its toxicity and irritation, obvious warning signs should be set up at storage and transportation places to remind personnel to pay attention to protection. Operators should wear appropriate protective equipment, such as gloves, goggles, gas masks, etc., to avoid direct contact and inhalation to ensure personal safety.
Fifth, isolated storage and transportation with other chemicals is also key. Due to its chemical properties or adverse reactions with certain substances, it is necessary to avoid mixing with oxidizing substances, alkaline substances, etc., to prevent danger.
