This substance is (chloromethyl) -2,3-divinylbenzene. Its chemical properties are as follows:
In this compound, the chloromethyl part has a certain activity. The chlorine atom can undergo a substitution reaction. Due to the strong electronegativity of the chlorine atom, the carbon-chlorine bond electron cloud is biased towards the chlorine atom, causing the carbon atom to be partially positively charged and vulnerable to attack by nucleophiles. For example, when co-heated with an aqueous solution of sodium hydroxide, the chlorine atom can be replaced by a hydroxyl group to form a compound containing hydroxyl groups.
The divinylbenzene part has the typical properties of olefins because it contains carbon-carbon double bonds. Addition reactions can occur, such as with the carbon tetrachloride solution of bromine, bromine can be added to the carbon-carbon double bond, so that the reddish brown of bromine fades; heating with hydrogen in the presence of a catalyst can occur hydrogenation reaction, and the double bond is reduced to a single bond. At the same time, the carbon-carbon double bond can also undergo polymerization reaction. Under the action of the initiator, multiple double bonds between the molecules are added to each other to form a polymer, which has important applications in the field of material synthesis.
In addition, the interaction between different groups in the molecule of the substance will have a subtle effect on its chemical properties. The electron-absorbing effect of chloromethyl may affect the distribution of the double-bond electron cloud in the part of divinylbenzene, which in turn affects the double-bond reactivity; and the electronic effect of the part of divinylbenzene may also affect the reactivity of chloromethyl substitution. The various chemical properties of this substance make it unique and valuable in many fields such as organic synthesis and material preparation.

Second, in the field of materials science, it may be able to participate in the synthesis of polymer materials. By appropriate polymerization, (benzyl) -2,3-dibromotoluene can be introduced into the polymer chain, giving the material special properties. For example, because of its aromatic ring structure, it may improve the thermal stability and mechanical properties of the material; the presence of bromine atoms may endow the material with certain flame retardancy, so that the prepared polymer materials can be used in electronic appliances, buildings and other fields that require fire resistance.
Third, it also has potential uses in drug development. Due to its special chemical structure, it may be used as a starting material for lead compounds. After chemical modification and optimization, drug molecules with specific biological activities may be created. Medicinal chemists can target specific disease targets, modify their structures, and explore their interactions with biomacromolecules in the hope of discovering new drugs with good pharmacological and pharmacokinetic properties.

If you want to make 1- (hydroxymethyl) -2,3-dihydroxypropionaldehyde medicine, you can follow the ancient method.
First take an appropriate amount of glycerol and place it in a clean kettle. Slow down the heat over low heat to gradually raise the temperature to a suitable degree. At this time, the glycerol molecules gradually move and the activity gradually becomes apparent.
Then, slowly inject the diluted hydrogen peroxide solution, which is a key move. When injecting, you need to carefully control the speed and keep stirring it to make the two fully mixed. Hydrogen peroxide reacts when it encounters glycerol, and the structure of the oxygen atoms interacts with the glycerol to start the molecular remodeling.
During the reaction, there may be fine bubbles escaping from the kettle, which is a sign of the reaction going on. It is necessary to observe it closely, control its temperature and reaction process, and do not overdo it.
When the reaction is coming to an end, move the resulting mixed liquid to a special filter to filter out unreacted impurities and obtain a clarified liquid.
Then, remove the excess water by low temperature and decompression. In this way, the purer 1- (hydroxymethyl) -2,3-dihydroxypropionaldehyde can be obtained.
The whole process requires strict compliance with the procedures and subtle changes to be observed before a good product can be obtained. From the selection of raw materials, to the control of the reaction, to the purification method, it is all about success or failure. Although the ancient method is long, it is exquisite, and it must be done carefully.

In the process of storage and transportation of mercury, all important items need to be paid attention to.
Mercury is highly toxic and poses a serious threat to the health of life and the ecology of the world. When storing, the first thing to do is to choose a well-sealed container to prevent it from evaporating and escaping. Commonly used are special mercury bottles, whose plugs must be tightly sewn to prevent mercury gas leakage. And the storage place should be cool and dry, far away from heat sources and open flames. Mercury is prone to disintegration due to heat, increasing the risk of diffusion.
During transportation, stability is essential. Mercury containers must be fixed securely to prevent them from breaking due to bumps and collisions. Transport equipment also needs special treatment to be leak-proof and corrosion-resistant. The escort must be familiar with the characteristics of mercury and emergency disposal methods. On the way, always check the sealing state of the container. If there is any leakage, deal with it quickly according to the procedures.
In addition, the storage and transportation of mercury should comply with strict laws and regulations. Record the amount, source and whereabouts of mercury in detail for inspection. The whole chain from mining and smelting to application needs to be strictly controlled, and mercury must not be allowed to enter the world wantonly.
The storage and transportation of mercury is related to the well-being of everyone and the peace of the world. Every detail should not be ignored. Only with caution can we ensure the harmony of the ecology and keep the tranquility of all beings.

(Mercaptomethyl) -2,3-dimercaptopropanol, the impact of this substance on the environment and human health is particularly important, as detailed below.
Mercaptomethyl-2,3-dimercaptopropanol, in the environment, if released in the soil, it may interact with minerals and organic matter in the soil due to its own chemical properties. Partial or adsorbed by soil particles, restricting its diffusion between soil pores, thereby affecting its range of action on surrounding organisms. In the water environment, its solubility may cause it to migrate in water, affecting aquatic ecosystems. Or toxic effects on aquatic plants, plankton, etc., interfering with their normal physiological metabolism, such as inhibiting photosynthesis, affecting respiration, etc., and then destroying the balance of aquatic food chains.
As for the impact on human health, the first to bear the brunt is the route of contact. Through skin contact, this substance may penetrate the skin barrier and cause skin irritation, such as erythema, itching, blisters and other symptoms. If inhaled carelessly, it will irritate the respiratory tract, causing cough, asthma in mild cases, and severe cases may cause respiratory inflammation, pulmonary edema and other serious diseases. If ingested by mistake, in the digestive system, it reacts with substances in the gastrointestinal tract, irritating the gastrointestinal mucosa, causing nausea, vomiting, abdominal pain, diarrhea and other discomfort.
Long-term low-dose exposure, in the human body, may interfere with the normal metabolic process of cells. The thiol groups contained in it can bind to a variety of metal ions in the body. Although the original intention may be to detoxify, excessive binding may change the balance of metal ions in the body, affecting the enzyme activity that relies on metal ions, such as zinc, copper and other metal enzymes, thereby interfering with normal physiological functions. In the long run, it may increase the risk of certain chronic diseases, such as liver and kidney function damage, because the liver and kidney are important organs for detoxification and metabolism, and bear the brunt of its impact. Therefore, when using and disposing of substances containing (mercaptomethyl) -2,3-dimercaptopropanol, extreme caution should be taken to protect the environment and human health.
