5-Alkane-2-enheptyl shows silver lung, and its chemical properties are as follows:
This substance has the general properties of alkenes, alkenes, and hydrocarbons containing carbon-carbon double bonds. The carbon-carbon double bond is its functional group, giving it active chemical properties.
The first word is an addition reaction, which can be added with various reagents. When encountering halogen elementals, such as bromine water, it can be added. The bromine-bromine bond in the bromine molecule is polarized by the electron cloud of the double bond. The partially positively charged bromine atom first binds to the carbon atom at one end of the double bond to form a carbon-positive ion intermediate, and then the negatively charged bromine ion quickly binds to the carbon-positive ion, and then the dibromine substitute is obtained. The reaction is fast and easy, and the phenomenon is obvious. The color of bromine water fades quickly, which can be used as a method to test olefins.
can also be added with hydrogen halide. According to the Markov rule, hydrogen atoms are mostly added to double-bonded carbon atoms containing more hydrogen, and halogen atoms are added to those containing less hydrogen. This is due to the different stability of the carbon cation of the reaction intermediate. Carbon cations containing more alkyl groups are more stable due to the effect of alkyl power supply, so the product has a specific orientation.
Complex can be added with water. Under acid catalysis, the double bond is protonated first to form carbon cations. Water molecules attack carbon cations and lose protons to obtain alcohol products.
In addition to addition to addition, there is still an oxidation reaction. When encountering strong oxidizing agents, such as acidic potassium permanganate solution, the carbon-carbon double bond breaks, and the products are different depending on the substituents at both ends of the double bond. If the double-bonded carbon atom is connected to two hydrogen atoms, it oxidizes to carbon dioxide; if it is connected to one hydrogen atom and one alkyl group, it forms carboxylic acid; if it is connected to two alkyl groups, it forms ketone. This reaction fades the potassium permanganate solution and is also a method for testing olefins.

Using its characteristic chemical reaction with specific substances, it is used to detect and quantitatively analyze certain compounds.

Although the specific mechanism of action is still being explored in depth, it has provided new research directions and ideas for drug development and other aspects.

To prepare 5-bromo-2-pentenal, the following ancient method can be used:
Take pentene first and bromide it. For pentenes, hydrocarbons with carbon-carbon double bonds can also react with bromine and double bonds. When the bromine vapor comes into contact with the pentene, under appropriate temperature and light, the bromine-bromine bond breaks, and bromine atoms are added to the carbon at both ends of the double bond to obtain 1,2-dibromopentane. During this process, attention must be paid to the reaction conditions. If the temperature is too high or too low, side reactions can occur.
Times, co-heat 1,2-dibromopentane with potassium hydroxide made from alcohol. Potassium hydroxide in alcohol can induce and eliminate the reaction. In this reaction, 1,2-dibromopentane removes two molecules of hydrogen bromide and weighs double bonds to obtain 2-pentene. The key to this step lies in the concentration of potassium hydroxide and the temperature of the reaction. Improper concentration or temperature is not suitable, or the reaction is difficult or there are by-products.
Then, use a mild oxidizing agent to aldehyde 2-pentene. Choose a weak oxidizing agent such as a mixture of manganese dioxide and dilute sulfuric acid. The α-hydrogen next to the double bond of 2-pentene can be oxidized to an aldehyde group under the action of a weak oxidizing agent. During the reaction, an oxidizing agent should be added slowly and stirred continuously to make the reaction proceed uniformly to prevent excessive oxidation.
After these steps, 5-bromo-2-pentenal can be obtained. Each step requires fine control of conditions. The purity of raw materials, the temperature of the reaction, and the amount of reagents are all related to the yield and purity of the product. Although the ancient steps are complicated, it is possible to obtain what is needed, which is the essence of chemical synthesis.

5-Bromo-2-pentenal ochre hydrazone is a strange medicine, and it should be used with caution, and there are many points to pay attention to.
First, this medicine has unique properties, and its color, taste, and state need to be carefully observed. When using it, you must carefully observe whether its color is correct, whether the taste is different, and whether the state is changed. If the color is mixed, the taste is strange, and the state is different, it is feared that the power of the medicine will change, or other diseases will occur, and it must not be used.
Second, when it comes to the dosage, you must not increase or decrease it yourself. You must follow the doctor's instructions, or follow the ancient rules. If the dosage is small, it will be difficult to achieve the effect of the medicine, and the disease will not be cured; if the dosage is large, it will be feared
Third, the time of medication should also be appropriate. Or before meals, or after meals, or at a specific time, all pay attention to it. Choose the time of medication according to the nature of the disease and the state of the body, so that the power of the medicine can reach the disease quickly and get twice the result with half the effort. If it is not at the time, although the medicine is good, it is difficult to show its ability.
Fourth, during the medication period, the diet should be avoided. Spicy, greasy, raw and cold things, or contrary to the medicine, or helping the disease. The food should be light and peaceful, so that the spleen and stomach can be healthy, and the essence of the medicine can be accepted by the body, and the medicine can be effective.
Fifth, pay attention to the reaction of the medicine. After medication, if the body has any symptoms such as itching, rash, vomiting, diarrhea, etc., it must be stopped immediately and reported to the doctor. This may be a discomfort of the medication or a sign of allergies. If it is not treated in time, it may cause serious harm.
In short, although 5-bromo-2-pentylenal ochre hydrazone can be used to help treat diseases, it needs to be used with caution. Observe the characteristics, control the dosage, choose the time, avoid diet, observe the reaction, and pay attention to all kinds of things to ensure the safety of medication and treat the disease without hurting the body.
