What are the physical properties of 3-Fluorobenzylamine?

3-Fluorobenzyl amine is also an organic compound. It has various physical properties, which are described in detail by you today.

In terms of its properties, 3-fluorobenzyl amine is a colorless to light yellow liquid at room temperature and pressure. It looks clear and has a special odor. Although this odor is not pungent, it is also unique and recognizable.

As for the boiling point, it is about 198-200 ° C. The boiling point is the temperature limit at which the substance changes from liquid to gaseous. This boiling point value shows that 3-fluorobenzyl amine needs to reach such a temperature before it can be reduced to gaseous state. < Br >
Its melting point is about -45 ° C. The melting point is the critical temperature for solid to liquid state. Below this temperature, 3-fluorobenzyl amine takes the form of a solid state, and above this temperature, it gradually melts into a liquid state.

In terms of density, it is about 1.074 g/mL at 25 ° C. In density, the mass of a unit volume of matter. This value reflects the mass of 3-fluorobenzyl amine per milliliter at a specific temperature.

Solubility is also an important property. 3-fluorobenzyl amine is slightly soluble in water, but easily soluble in common organic solvents such as ethanol and ether. This is due to the characteristics of its molecular structure, which is compatible with the force between organic solvent molecules, so it dissolves well; the force between water molecules is slightly weaker, resulting in limited solubility in water.

And its refractive index is about 1.521 - 1.523. The ratio of the sine of the incident angle to the sine of the refractive angle when light propagates in the medium reflects the refractive ability of the substance to light. This value is an important basis for identifying 3-fluorobenzyl amine.

The above are all the physical properties of 3-fluorobenzyl amine. In many fields such as chemical industry and medicine, these properties are of critical use, and are related to its preparation, separation, and application.

What are the chemical properties of 3-Fluorobenzylamine?

3-Fluorobenzylamine is an organic compound with unique chemical properties, which is worth exploring. This substance contains fluorine atoms and benzylamine structures, and the introduction of fluorine atoms often gives molecular-specific properties.

It is alkaline, because nitrogen atoms have lone pairs of electrons, which can accept protons, and can form salts in acidic environments. This alkalinity makes 3-Fluorobenzylamine neutralize with acids to generate corresponding salts, which can be used in organic synthesis, or can be used to realize the separation and purification of compounds.

From the perspective of nucleophilicity, the lone pairs of electrons of nitrogen atoms also make 3-Fluorobenzylamine nucleophilic and can participate in nucleophilic substitution reactions. For example, when encountering halogenated hydrocarbons, nitrogen atoms will attack the carbon atoms of halogenated hydrocarbons, and the halogen atoms will leave to form new carbon-nitrogen bonds, thereby forming a variety of nitrogen-containing organic compounds, which are widely used in drug synthesis and materials science.

The benzyl part of its molecule has certain stability and spatial structure characteristics. The presence of benzyl groups may affect the physical properties of molecules, such as solubility, melting point and boiling point. At the same time, the benzyl ring of benzyl can participate in π-π stacking, which affects the self-assembly behavior of molecules in supramolecular chemical systems.

Because of the fluorine atom, 3-Fluorobenzylamine has special electronic effects. Fluorine atoms are highly electronegative, which attracts electrons and alters the distribution of molecular electron clouds. This electronic effect may affect the reactivity and selectivity of reactions, allowing them to exhibit unique chemical behaviors in certain reactions, providing organic synthesis chemists with novel strategies to create organic molecules with specific functions.

What are the synthesis methods of 3-Fluorobenzylamine?

3-Fluorobenzamide is an important intermediate in organic synthesis. There are various ways to synthesize it.

First, 3-fluorobenzoic acid is used as the starting material. First, 3-fluorobenzoic acid is co-heated with dichlorosulfoxide to obtain 3-fluorobenzoyl chloride. This reaction needs to be carefully controlled to prevent side reactions. After 3-fluorobenzoyl chloride reacts with excess ammonia at low temperature, 3-fluorobenzamide can be obtained. Finally, 3-fluorobenzamide is reduced in an anhydrous ether environment with lithium aluminum hydride as a reducing agent to obtain 3-fluorobenzamide. Although this step is a little complicated, the raw materials are easy to obtain and the reaction has good controllability.

Second, 3-fluorobrobenzyl is used as the starting material. React 3-fluorobrobenzyl with potassium phthalimide in a polar solvent such as DMF to form N - (3-fluorobenzyl) phthalimide. Then N - (3-fluorobenzyl) phthalimide is treated with hydrazine hydrate, and the ring is untied with water to obtain 3-fluorobenzyl amine. The reaction conditions of this route are mild and the yield can be observed.

Third, 3-fluorotoluene is used as the starting material. First, 3-fluorotoluene undergoes side chain substitution reaction with bromine in the presence of light or initiator to obtain 3-fluorobenzyl bromide. After that, 3-fluorobenzyl bromide is co-heated with ammonia alcohol solution, and 3-fluorobenzyl amine can be prepared by nucleophilic substitution reaction. The steps of this method are simple, but the selectivity of side chain substitution should be paid attention to to to prevent the formation of polybrominates.

All synthesis methods have their own advantages and disadvantages. In practical application, the appropriate method is carefully selected according to factors such as raw material availability, cost, reaction conditions and product purity.

What to pay attention to when storing and transporting 3-Fluorobenzylamine

3-Fluorobenzyl amine is an organic compound. When storing and transporting, many matters need to be paid attention to.

First words storage. This substance has a certain chemical activity, so it should be stored in a cool, dry and well-ventilated place. Due to heat, it is easy to cause chemical reactions to intensify, and even cause danger, so it should be kept away from fire and heat sources. If placed in a humid environment, or interact with water vapor, it may affect its chemical properties, so moisture protection is extremely critical. And it needs to be stored in an airtight container to prevent excessive contact with air, causing oxidation or reaction with air components. In addition, the storage place should be separated from oxidizing agents, acids, etc., to avoid contact between different chemical substances and cause uncontrollable reactions.

As for transportation, there are also many details. Before transportation, it is necessary to ensure that the packaging is intact, and the packaging materials used must be able to resist general collisions and vibrations to prevent leakage. During transportation, vehicles should be equipped with corresponding fire equipment to prevent accidents and respond in time. Drivers and escorts must be familiar with the chemical properties of 3-fluorobenzamine and emergency treatment methods. When driving, avoid high temperature periods and routes to prevent adverse effects on goods due to excessive temperature. During transportation, it is necessary to pay close attention to the status of the goods. Once damage or leakage of the packaging is found, effective measures should be taken immediately, such as evacuating the crowd, sealing the scene, and promptly reporting to the relevant departments. They should be properly handled according to professional guidance. Do not slack off to avoid serious consequences.
