3-Iodo-1H-indazole is an organic compound with unique physical properties. It is a solid at room temperature. Due to intermolecular forces and structural characteristics, the melting point is relatively high, about 180-182 ° C. This melting point enables it to maintain a stable solid state under specific temperature conditions. In related experiments and applications, there are certain requirements for the operating temperature range.
The appearance of the compound is like a white to light yellow crystalline powder. This appearance characteristic is not only convenient to preliminarily judge its purity and state by naked eye observation, but also helps to distinguish it from other substances with different appearances in actual operation.
Its solubility is slightly soluble in water. This is due to the strong polarity of water molecules and the relatively weak polarity of 3-iodo-1H-indazole molecules. According to the principle of similarity and miscibility, the interaction between the two is weak, resulting in its insolubility in water. However, it is soluble in some organic solvents, such as dichloromethane, N, N-dimethylformamide (DMF), etc. This solubility characteristic provides a basis for the selection of suitable reaction solvents in organic synthesis experiments. It can take advantage of its solubility differences in different solvents to achieve separation and purification operations.
3-iodo-1H-indazole also has certain stability. Under normal storage conditions, as long as high temperature, strong light and contact with strong oxidants, strong acids and bases and other active substances are avoided, the chemical structure and properties can be maintained for a long time. However, under specific chemical reaction conditions, such as in some organic synthesis reactions, affected by factors such as reagents, temperature, catalysts, etc., the iodine atoms and indolazole rings in its structure will show corresponding reactivity and participate in various chemical reactions.

3-Iodo-1H-indazole is an organic compound, and its common synthesis methods are as follows:
The starting material is often based on 1H-indazole, which is used as the skeleton, and the iodine atom is added above the 3-position.
The first method is halogenation. First dissolve 1H-indazole in a suitable solvent, such as dichloromethane, N, N-dimethylformamide (DMF). The solvent needs to be pure and anhydrous to prevent impurities from disturbing the reaction process. Subsequently, add a halogenating agent, such as N-iodosuccinimide (NIS). NIS is excellent because of its suitable reactivity and can introduce iodine atoms precisely at the 3-position. The reaction system needs to be temperature-controlled, usually at low temperatures, such as between 0 ° C and room temperature. If the temperature is too high, it is easy to cause side reactions of polyhalogenation; if it is too low, the reaction will be delayed. In this process, a catalyst can be added, such as the initiator azobisisobutyronitrile (AIBN). AIBN can promote the formation of free radicals and speed up the reaction rate. During the reaction, continue to stir to make the material mix evenly, so that the iodine atoms can fall into just 3 positions.
Another method is to catalyze with transition metals. Salts of metals such as palladium and copper are selected as catalysts, such as palladium acetate and cuprous iodide. Metal salts can activate the substrate and increase its reactivity. Ligands are also indispensable, such as bipyridine The ligand complexes with the metal to stabilize the active center and adjust the selectivity of the reaction. The 1H-indazole reacts with iodine sources, such as iodine elemental or iodine aromatic hydrocarbons, in an alkaline environment. The base can capture the hydrogen of the substrate and increase its nucleophilicity. Common bases include potassium carbonate, sodium carbonate, etc. The reaction is carried out in an organic solvent, such as toluene, dioxane, with temperature control in an appropriate range, or heated to reflux. Through metal catalysis, iodine atoms can be efficiently and selectively connected to the third position of 1H-indazole to obtain 3-iodo-1H-indazole.
These two methods have their own advantages and disadvantages. The halogenation reaction step is simple and the conditions are easy to control; the transition metal catalysis method has excellent selectivity and higher yield. The experimenter should synthesize 3-iodo-1H-indazole according to the need.
