3-quinolinecarbonitrile, 4-hydroxy-

4-Hydroxy-3-quinolinoformonitrile, this property belongs to the category of organic chemistry. Its color state, mostly crystalline powder at room temperature, the appearance may be white to light yellow, the texture is fine, and the morphology is stable due to the regular and orderly arrangement of molecules.
In terms of solubility, it has a certain solubility in polar organic solvents such as dimethyl sulfoxide (DMSO) and N, N-dimethylformamide (DMF), because these solvents and the compound can form intermolecular forces to help it disperse and dissolve; while the solubility in water is very small, because its molecular polarity and water molecules are not well matched, and the interaction is weak.
In terms of thermal stability, the structure is stable within a certain temperature range. When it reaches a certain temperature, the molecular vibration intensifies, and chemical bonds or raw fracture rearrangements are rearranged, triggering decomposition reactions. The decomposition temperature varies according to factors such as purity and crystal form, and it usually needs to be accurately determined by professional thermal analysis instruments such as thermogravimetric analyzers.
The chemical activity is quite significant. The 4-hydroxyl group has an active hydrogen atom, which is easy to participate in substitution reactions, such as reacting with halogenated hydrocarbons to form ether derivatives. The 3-formonitrile group has strong electron absorption, which changes the distribution of molecular electron clouds, which not only affects the reactivity, but also participates in characteristic reactions of nitrile groups, such as hydrolysis to form carboxyl groups, or addition with nucleophiles to form new < Br >
Spectral characteristics are also important physical properties. In the infrared spectrum, 4-hydroxyl groups have specific stretching vibration absorption peaks, which can be used for structural characterization; methonitrile groups also have corresponding characteristic peaks, which help to determine their existence. In the ultraviolet-visible spectrum, due to the existence of the conjugate system, there are absorption peaks at specific wavelengths, which can be used for qualitative and quantitative analysis.

4-Hydroxy-3-quinolinoformonitrile, this substance has the following physical properties. Its appearance is often crystalline powder, and the color may be white to light yellow. This is because its molecular structure contains a conjugated system. The degree of conjugation affects the electron transition energy level, which in turn affects the absorption of light, and determines the color and morphology.
Melting point is about 230-235 ° C. Due to the presence of hydrogen bonds, van der Waals force and other forces between molecules, heating needs enough energy to overcome. This temperature range can destroy the lattice, and the substance changes from solid to liquid.
Solubility, slightly soluble in water. The reason is that although there are hydroxyl groups in the molecule that can form hydrogen bonds with water, the quinoline ring and cyanyl group are hydrophobic groups, and the overall hydrophobic effect is dominant, so the solubility in water is small. However, it is more soluble in common organic solvents, such as dichloromethane, N, N-dimethylformamide (DMF), etc. Because these organic solvents can form similar forces with the molecules of the substance, according to the principle of "similar miscibility", they are more easily miscible. These physical properties of

To prepare 3-quinoline formonitrile and 4-hydroxyl group, there are various wonderful methods, which can be found from the classical organic synthesis.
First, the compound containing the quinoline structure is used as the starting material. Before the appropriate reaction conditions, the specific position of the quinoline ring is modified to introduce a nitrile group. The introduction of the nitrile group can be reacted by nucleophilic substitution. For example, the halogenated quinoline is selected, and it reacts with cyanide-containing reagents, such as potassium cyanide or sodium cyanide, in the presence of appropriate solvents and catalysts. In this case, the solvent needs to have good solubility to the reactants and does not interfere with the reaction process, and the catalyst can accelerate the reaction rate, such as some transition metal catalysts.
Furthermore, the formation of hydroxyl groups You can start with quinoline derivatives containing suitable protective groups and deprotect them to obtain hydroxyl groups. Or when the quinoline ring is constructed, the hydroxyl group introduction steps are planned. If there are suitable functional groups, hydrolysis, oxidation and other reactions can be used to convert specific groups into hydroxyl groups.
There is another way to start with the construction of the quinoline ring. Through multi-step reactions, the quinoline parent nucleus is first built, and the nitrile and hydroxyl groups are precisely introduced during the construction process. This requires a skilled grasp of various reaction mechanisms for the construction of quinoline rings, such as Skraup reaction, Doebner-von Miller reaction, etc., and a reasonable design of the order of group introduction in the reaction steps to make each reaction proceed smoothly, and finally obtain the target product 3-quinoline formonitrile, 4-hydroxy. Each step of the reaction requires attention to the control of reaction conditions, such as temperature, pH, reaction time, etc., in order to achieve the best reaction effect and improve product purity and yield.
