Isoquinoline-1-formaldehyde is a kind of organic compound. It has unique physical properties, which are described as follows:
Under normal temperature and pressure, isoquinoline-1-formaldehyde is a light yellow to yellow crystalline powder or crystal. This morphological feature can be seen and touched, which is its external characterization.
When it comes to the melting point, it is in the range of 56-59 ° C. The characteristics of the melting point are caused by the interaction of factors such as intermolecular forces and lattice structure. When the temperature rises to a specific value, the lattice energy is overcome, and the substance changes from a solid state to a liquid state.
In terms of boiling point, it is about 305.8 ° C. The boiling point is affected by factors such as the attractive force between molecules and the relative molecular mass. At the boiling point, the saturated vapor pressure of the liquid is equal to the external atmospheric pressure, and the substance changes from liquid to gaseous state.
Isoquinoline-1-formaldehyde is slightly soluble in water, and this solubility comes from its molecular structure. Although there is a polar aldehyde group, the hydrophobicity of the isoquinoline ring is dominant, making it insoluble in polar water. However, it is soluble in organic solvents such as ethanol, ether, and chloroform. Due to the principle of "similarity and miscibility", the compound is similar to the organic solvent in terms of molecular polarity and structure, so it can be miscible.
This compound has a certain stability in the air. However, due to the active chemical properties of aldehyde groups, long-term exposure may react with oxygen and other components in the air and cause deterioration. When storing, it should be placed in a cool, dry and well-ventilated place, and it needs to be sealed to prevent excessive contact with the air.
The above physical properties are of great significance in organic synthesis, medicinal chemistry and other fields. For example, in organic synthesis, according to its melting point, solubility and other properties, suitable reaction solvents and reaction conditions can be selected to achieve the expected reaction effect; in medicinal chemistry, with its physical properties, or a reasonable drug dosage form can be designed to optimize the absorption and distribution of drugs.

To prepare isoquinoline-1-formaldehyde, the following method can be used.
First, isoquinoline is used as the starting material. First, isoquinoline and N-bromosuccinimide (NBS) are heated in a suitable solvent, such as carbon tetrachloride, in the presence of an initiator such as benzoyl peroxide. This step aims to introduce the 1-position of isoquinoline into the bromine atom to obtain 1-bromoisoquinoline. After the reaction is completed, pure 1-bromoisoquinoline is obtained by separation and purification methods, such as column chromatography. < Br >
Then, 1-bromoisoquinoline is combined with carbon monoxide, a palladium catalyst (such as tetra (triphenylphosphine) palladium) and a suitable base, such as potassium carbonate, in an organic solvent such as N, N-dimethylformamide (DMF), heated and reacted under a certain pressure. This reaction is a carbonylation process, which can replace the bromine atom with an aldehyde group to obtain isoquinoline-1-formaldehyde. After the reaction is completed, the product can be obtained by means of extraction and distillation.
Second, 1-methylisoquinoline can also be used as a raw material. 1-Methyl isoquinoline and selenium dioxide are heated and refluxed in an organic solvent such as dioxane. Selenium dioxide can selectively oxidize methyl groups to aldehyde groups to obtain isoquinoline-1-formaldehyde. After the reaction is completed, the product is purified by filtration of solids and decompression distillation.
The preparation method requires attention to the control of reaction conditions, such as temperature, pressure, and the proportion of reactants. The purification operation after each step of the reaction is also crucial, which is related to the purity and yield of the product.
