3%2C4+-+Quinolinediamine%2C2+-+Chloro+-+N4+-+%282+-+Methylpropyl%29, this is the English name of the chemical substance, and the corresponding Chinese may be 2-chloro-N4- (2-methylpropyl) -3,4-quinoline diamine. Its physical properties are as follows:
This compound has unique physical properties due to the specific structure of chlorine atoms, amine groups and quinoline rings. In appearance, it is often presented in solid form, and the specific color may vary due to differences in purity and crystal form, mostly white to light yellow crystalline powder. This is due to intermolecular forces and electron transition characteristics.
From the melting point point point of view, in view of the rigid structure of the quinoline ring and the hydrogen bonding between molecules, the melting point is relatively high, generally in the range of 150-200 ° C. In this temperature range, the molecule obtains enough energy to overcome the lattice energy, thus transforming from a solid state to a liquid state.
In terms of solubility, because it contains polar amine groups, it has a certain solubility in polar organic solvents such as ethanol and acetone. However, due to the existence of quinoline rings and methyl propyl groups, its solubility in water is limited. This solubility characteristic is derived from the principle of similar miscibility. Polarity partially facilitates interaction with polar solvents, while non-polar groups hinder dissolution in water.
Its density is also affected by the compactness of the molecular structure, which is roughly between 1.2 and 1.4 g/cm ³. The degree of compactness formed by the type of atoms and the connection mode in the molecule determines the mass size per unit volume.
The above are the common physical properties of 2-chloro-N4- (2-methylpropyl) -3,4-quinoline diamine, which are crucial for its application in chemical synthesis, drug development and other fields.

From the structural point of view, the quinoline ring system endows it with a certain rigidity and conjugate system, so that the molecule has a specific electron distribution and stability. The chlorine atom is introduced at the 2 position, because of its large electronegativity, it has a significant impact on the distribution of molecular electron clouds, enhances electrophilicity, makes this site prone to nucleophilic substitution, and affects molecular polarity, changing its solubility and intermolecular forces.
N4-linked 2-methylpropyl is an alkyl group, which has an electron-induced effect, which increases the electron cloud density of nitrogen atoms, enhances its alkalinity, and exhibits unique activity in acid-base reactions. This alkyl group also increases the molecular steric resistance, which affects the reaction selectivity and the way of molecular stacking.
In terms of physical properties, due to the coexistence of polar groups and non-polar groups in the structure, its solubility may be between polar and non-polar solvents. The melting point and boiling point are subject to intermolecular forces. The conjugated system and polar groups enhance the intermolecular forces, and the melting boiling point may be relatively high.
Chemically, in addition to the nucleophilic substitution reactions mentioned above, amino groups are alkaline and can form salts with acids. The double bond of the quinoline ring can participate in the addition reaction, and under suitable conditions and reagents, it exhibits a variety of chemical reactivity, providing the possibility for the construction of complex structures in organic synthesis.
Overall, the structure of 2-chloro-N4- (2-methylpropyl) -3,4-quinolinediamine determines its active and diverse chemical properties, and has potential application value in organic synthesis, pharmaceutical chemistry and other fields.

3%2C4+-+Quinolinediamine%2C2+-+Chloro+-+N4+-+%282+-+Methylpropyl%29, that is, 2-chloro-N4- (2-methylpropyl) -3,4-quinoline diamine, the preparation method is very complicated, let me elaborate.
To prepare this substance, the corresponding quinoline derivative is often used as the starting material. First, quinoline is used as the base, and the chlorine atom is introduced into the 2 position by the halogenation method. When halogenating, when selecting a suitable halogenating agent, such as a chlorine-containing halogenating agent, under the appropriate reaction conditions, the chlorine atom is precisely replaced. The choice of temperature and solvent is related to the success or failure of the reaction and the yield. < Br >
Then, to introduce the N4- (2-methylpropyl) group, an amination reaction is required. An amine reagent containing 2-methylpropyl can be selected and reacted with the halogenated quinoline derivative with the help of a catalyst. This catalyst, either a metal salt or an organic base, functions to promote the reaction and reduce the activation energy of the reaction. When reacting, pay attention to the reaction process to prevent side reactions.
After the reaction, the product often contains impurities, which need to be separated and purified. The method of recrystallization can be used, and a suitable solvent can be selected to dissolve the product in it, and then slowly crystallize to remove impurities. Or use column chromatography to achieve the purpose of separation according to the polarity difference between the product and the impurities.
This preparation method requires careful steps, and the reaction conditions, the selection of reagents, and the separation and purification techniques are all key. A little carelessness will affect the purity and yield of the product.
