Cupric 8-oxyquinoline, that is, 8-hydroxyquinoline copper, has unique physical properties. At room temperature, it is often solid and yellow-green in color. It looks like emerald jade and has its own beauty of color.
In terms of its density, it is relatively large, and it can be felt that it is heavy in quality and seems to contain profound power. Its melting and boiling point is also quite considerable, and its melting point is high. It requires intense heat to transform its shape, just like it has been tempered to transform. In terms of boiling point, it also needs a sufficient supply of energy to turn it into a gaseous state.
Furthermore, 8-hydroxyquinoline copper is insoluble in water, and it is difficult to dissolve it in the clear waves of water. However, in some organic solvents, it can gradually melt into it, showing affinity for specific solvents. When it is in the solid state, its structure is relatively stable, and the molecules interact closely, like building a strong fortress. Under light, its surface may reflect a unique luster, adding a bit of mysterious charm. And because of its physical properties, it can exert its capabilities in many fields, and has outstanding performance in material protection, catalysis, etc., contributing to the development of related technologies.

Cupric 8-oxyquinoline, that is, 8-hydroxyquinoline copper. The chemical properties of this substance are quite stable. The reason is that in the structure of 8-hydroxyquinoline, both nitrogen atoms and oxygen atoms have lone pairs of electrons, which can form stable coordination bonds with copper ions. This coordination compound forms a relatively regular ring structure within the molecule, which is maintained by coordination bonds and intramolecular forces, which greatly increases its chemical stability.
When in a general chemical environment, it is not easy for external reagents to destroy this coordination structure and initiate a reaction. For example, in the common acid-base environment, if there is no strong acid-base or specific coordination agent intervention, its structure is difficult to change significantly. Even when encountering redox reagents, if the oxidation or reduction does not reach a certain degree, it is difficult to break the stable coordination system.
Furthermore, from the perspective of its crystal structure, the intermolecular arrangement is orderly, which further enhances its stability. The lattice can optimize the interaction between molecules and hinder the occurrence of relative motion and chemical changes between molecules.
Therefore, in general, Cupric 8-oxyquinoline is chemically stable, and its structure and properties can be maintained relatively constant in many common chemical scenarios.

The method for preparing Cupric-8-oxyquinoline (8-hydroxyquinoline copper) is described below.
Prepare the required materials first, including copper sulfate ($CuSO_ {4} $) and 8-hydroxyquinoline ($C_ {9} H_ {7} NO $), and the amount should be precise. Take an appropriate amount of copper sulfate, dissolve it in an appropriate amount of pure water, stir it, make it completely soluble, and form a blue and transparent copper sulfate solution. 8-hydroxyquinoline is also dissolved in an appropriate organic solvent, such as ethanol, stir to help dissolve, until it is uniformly dispersed in the solvent. < Br >
Then, pour the solution of 8-hydroxyquinoline into the copper sulfate solution slowly, and stir it slowly and continuously to make the two fully miscible. During this process, a chemical reaction will take place in the solution, and a precipitation will gradually develop. This precipitation is 8-hydroxyquinoline copper.
After the reaction is completed, let it stand for a while to allow the precipitation to settle. Then use a suitable filter, such as filter paper or sand core funnel, to filter and leave the precipitation on the filter.
If the precipitation is obtained, wash it several times with an appropriate amount of organic solvent, such as ethanol, to remove impurities. After washing, remove the precipitate to a suitable container and dry it at a suitable temperature, such as in an oven, at about 60-80 ° C, until the precipitate is constant weight, to obtain pure Cupric-8-oxyquinoline. The whole process should pay attention to the specifications of the operation to ensure the purity and quality of the product.

When using Cupric 8-oxyquinoline (8-hydroxyquinoline copper), there are many points to pay attention to.
First, safety protection must be comprehensive. This substance may be toxic and irritating. During operation, you need to wear protective clothing, gloves and goggles to prevent direct contact with the skin and eyes. In case of inadvertent contact, you should immediately rinse with a lot of water and seek medical assistance according to the specific situation. The operation site should also ensure good ventilation to avoid inhalation of its dust or volatile gases to prevent respiratory tract irritation or poisoning.
Second, precisely control the dosage. According to specific uses and needs, use in strict accordance with the specified dosage. If the dosage is too small, or it is difficult to achieve the desired effect; if the dosage is too large, it will not only cause waste, but also may cause negative effects, such as pollution to the environment, or affect subsequent reactions or product quality in specific application scenarios.
Third, storage conditions cannot be ignored. It should be stored in a dry, cool and ventilated place, away from fire and heat sources. At the same time, it should be stored separately from oxidants, acids and other substances to prevent chemical reactions. The storage container should be well sealed to avoid moisture or deterioration due to reaction with air components, which will affect the performance of use.
Fourth, pay attention to compatibility taboos. During use, it is necessary to clarify its compatibility with other substances. Some chemical substances mixed with it may produce precipitation, reduce efficacy or cause other adverse reactions. Before using with new substances, it is advisable to conduct small-scale tests to confirm that there are no adverse effects before large-scale application.
