As for the melting point, it is about 155-159 ° C. Determination of the melting point is an important means to identify this substance and determine its purity. When the temperature gradually rises to a specific range, the substance changes from solid to liquid, and this melting point characteristic is constant, which can be used as its inherent identification.
In terms of solubility, 1-hydroxyisoquinoline exhibits good solubility in organic solvents such as ethanol and dichloromethane. The polarity and molecular structure of ethanol make it interact with 1-hydroxyisoquinoline, and the molecules can be uniformly dispersed; dichloromethane can also dissolve this compound due to its own characteristics. However, in water, its solubility is not good. The polarity of water is quite different from the structure of 1-hydroxyisoquinoline, and the interaction force between the two makes it difficult for the compound to disperse in water, only slightly soluble.
In addition, 1-hydroxyisoquinoline has a certain density. Although the exact value needs to be determined according to specific conditions, its density characteristics also play an important role in many chemical operations and practical applications, related to the mixing, separation and other processes of substances. Under normal conditions, its stability is acceptable, but it may also undergo chemical changes under conditions such as specific chemical reagents, high temperature or strong light, which is based on the activity of the functional groups contained in its molecular structure.

1-Hydroxyisoquinoline is one of the organic compounds. Its properties are weakly acidic, and the hydroxyl group can release protons, so it is also. In the field of chemical reaction, it can interact with bases to form corresponding salts. This reaction is a common example of acid-base neutralization. The hydrogen of the hydroxyl group combines with the hydroxide in the base to form water, and the rest form salts.
It has nucleophilic properties, which is due to the high electron cloud density of nitrogen atoms and hydroxyl groups. Therefore, it can react with electrophilic reagents. In case of halogenated hydrocarbons, nitrogen or oxygen atoms can attack the carbon of halogenated hydrocarbons, and the halogen ions leave to form new compounds. This is the path of nucleophilic substitution. < Br >

The synthesis method of 1-hydroxyisoquinoline has been explored by many scholars in the past. The present number method is as follows.
First, isoquinoline is used as the starting material and can be obtained by oxidation. If in a suitable solvent, add a suitable oxidant, such as peroxide. Hydrogen in the ortho position of the nitrogen atom of isoquinoline can be oxidized under the action of an oxidant, and then hydroxyl groups are introduced. However, the reaction conditions need to be carefully regulated. Temperature, reaction time and oxidant dosage are all related to the yield and purity of the product.
Second, it is prepared by the cyclization reaction of aromatic amines and halides. First, the nucleophilic substitution reaction occurs between the aromatic amine and a specific halogen under the catalysis of a base, and then the molecule is cyclized to construct an isoquinoline ring, and then the hydroxyl group is introduced at a specific position through appropriate steps. In this process, the selection of the halogen, the type and dosage of the base, and the optimization of the cyclization conditions are all key.
Third, the phenylacetonitrile derivative is used as the starting material to construct the isoquinoline skeleton through a multi-step reaction and introduce the hydroxyl group. First, the phenylacetonitrile derivative is modified, such as condensation reaction with suitable reagents, and then a series of steps such as cyclization and oxidation can obtain 1-hydroxyisoquinoline. This route is a bit complicated, but the selectivity and yield of each step can be optimized by carefully designing the reaction conditions, such as selecting the appropriate catalyst, solvent and reaction temperature, in order to make the reaction proceed smoothly and achieve the purpose of synthesis.

1-Hydroxyisoquinoline, when storing and transporting, be sure to pay attention to many matters.
First word storage. This substance should be stored in a cool, dry and well-ventilated place. Because it may be sensitive to humidity and temperature, if the environment is humid and warm, it may change its properties and even deteriorate. Therefore, a dry place must be selected to prevent the risk of moisture dissolution. And it should be kept away from fire and heat sources. Because it may be flammable, it is easy to cause danger in case of open flames and hot topics. In addition, it needs to be stored separately from oxidants, acids, alkalis, etc., to avoid mixed storage. Due to its active chemical properties, contact with various chemicals, or severe chemical reactions, endangering safety.
As for transportation, there is also attention to it. Before transportation, be sure to ensure that the packaging is complete and well sealed to prevent leakage during transportation. When handling, it should be handled lightly, and it must not be loaded and unloaded brutally, so as not to damage the packaging and cause leakage of 1-hydroxyisoquinoline. During transportation, the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment should be equipped. If a leak occurs during transportation, emergency measures should be taken immediately, and people should be evacuated from the surrounding area to avoid contact with the leak. And transportation vehicles should follow the specified route, and do not stop in densely populated areas and open flames to ensure safety. In short, when storing and transporting 1-hydroxyisoquinoline, be cautious and strictly abide by the norms to keep it safe.
