Looking at its structure, the bromine atom and the methoxy group are connected to the isoquinoline ring. The bromine atom is active and often plays an important role in nucleophilic substitution reactions. Because of its high electronegativity, the connected carbon is partially positively charged and vulnerable to attack by nucleophilic reagents, such as with alkoxides, amines and other nucleophilic reagents, which can be substituted to form new compounds, which is of great significance in the expansion of organic synthesis pathways. The presence of the methoxy group
also affects the properties of this compound. The methoxy group is the electron cloud density of the isoquinoline ring, which can increase the electron cloud density of the isoquinoline ring through the conjugation effect, making it more prone to electrophilic substitution reaction, and the reaction check point is preferred, mostly with small in-situ resistance and significant increase in electron cloud density.
In terms of physical properties, the compound may be a solid at room temperature due to factors such as intermolecular forces, and has a certain melting point. Its solubility or due to the polarity of bromine and methoxy groups, it has good solubility in organic solvents such as dichloromethane and chloroform, but poor solubility in water. This property needs to be taken into account when separating, purifying and selecting the reaction medium. The chemical properties of 1-bromo-4-methoxy isoquinoline are derived from its specific structure. With the reactivity of bromine and methoxy groups in the field of organic synthesis, many organic molecules with novel structures can be constructed, which contributes to the research of organic chemistry and the development of related industries.

Chemists can take advantage of the activity of bromine atoms to carry out nucleophilic substitution reactions, introduce various nucleophilic reagents, and expand the structural complexity of molecules. Its methoxy group can play a localization effect in the reaction, guide the selectivity of the reaction check point, and help to construct exquisite organic molecules. And the stability and unique reactivity of the isoquinoline skeleton provide a strong foundation for the synthesis of complex natural products or functional materials. Through multi-step reactions, the transformation from simple starting materials to complex molecules with specific functions can be realized. In materials science, new materials with special optical and electrical properties may be prepared.

The synthesis of 1-bromo-4-methoxy isoquinoline is an important topic in the field of organic synthesis. The synthesis of this isoquinoline follows multiple methods, one of which is as follows:
Starting material, the appropriate isoquinoline derivative can be selected. This derivative needs to have a group that can be converted to methoxy at 4 positions and an activity check point that can be introduced into bromine atoms at 1 position.
First, methoxylation is performed at 4 positions. In this step, a suitable methoxylating agent, such as methyl halide (such as iodomethane) and a base (such as potassium carbonate), can be selected to react in an organic solvent (such as N, N-dimethylformamide, DMF). This reaction condition is mild, and the base can capture the active hydrogen at the 4 position of the substrate, and then undergo nucleophilic substitution reaction with the methyl halide, and the methoxy group is introduced at the 4 position.
After the methoxy group is successfully introduced at the 4 positions, the 1 position is brominated. The bromination process can be selected with brominating reagents, such as N-bromosuccinimide (NBS), and benzoyl peroxide (BPO) is used as the initiator, and heated in a suitable solvent (such as carbon tetrachloride, CCl). This reaction uses a free radical mechanism. Under the action of the initiator, NBS produces bromine free radicals, which then attack the isoquinoline 1 position to form 1-bromo-4-methoxy isoquinoline.
After the reaction is completed, the product is often mixed with impurities and needs to be separated and purified. Column chromatography can be used to use silica gel as the stationary phase and a suitable eluent (such as the mixed solvent of petroleum ether and ethyl acetate) for elution. According to the different partition coefficients of each component in the stationary phase and mobile phase, the purpose of separation and purification can be achieved. Finally, pure 1-bromo-4-methoxyisoquinoline can be obtained.

For 1-bromo-4-methoxyisoquinoline, many things need to be paid attention to during storage and transportation. This is an organic compound with unique properties. If you are not careful, it will cause disaster.
First of all, for storage, you need to find a cool, dry and well-ventilated place. Because it is more sensitive to heat, under high temperature, it may decompose and cause quality damage, so it must not be placed in direct sunlight or high temperature. And it should be stored in isolation from oxidants, strong bases and other substances. In the structure of 1-bromo-4-methoxy isoquinoline, the bromine atom is connected to the methoxy group in the isoquinoline ring, and the oxidizing agent or oxidation reaction occurs, and the strong base may also react with it, such as nucleophilic substitution, which can damage its structure.
Furthermore, the packaging must be tight and reliable. It is often packed in glass or special plastic containers and tightly sealed to prevent leakage. Once it leaks, it not only wastes materials, but also has certain toxicity and irritation, or endangers the surrounding environment and personal safety.
As for transportation, it should not be sloppy. Transportation vehicles must be equipped with corresponding fire and emergency treatment equipment. During driving, avoid bumps and vibrations to prevent package damage. Escort personnel also need to be familiar with the characteristics of this object and emergency response methods. When loading and unloading, handle it with care, and strictly prohibit touching or dragging to ensure that the goods are intact.
In this way, the storage and transportation of 1-bromo-4-methoxyisoquinoline can ensure its safety and quality.

For 1-bromo-4-methoxyisoquinoline, it is difficult to determine the range of its market price. This compound may have applications in various fields of chemical industry, but its price often varies due to many reasons.
First, the preparation is difficult and easy. If the preparation method is complicated, rare raw materials and exquisite craftsmanship are required, and the price will be high. If the required raw materials are not easy to obtain, or there are many fine controls in the preparation process, the cost will increase greatly, resulting in high market prices.
Second, the amount of demand. If there is strong demand in fields such as pharmaceutical research and development and material science, but the supply is limited, the price will also rise. On the contrary, if there is little demand and the manufacturer produces less, the price may remain high due to cost sharing, or decrease due to the desire to sell quickly.
Third, market competition. If there are many suppliers in the market, the competition is fierce with each other, and the price may become easier for customers. If there are few suppliers, it is almost a monopoly, and the price can be higher.
Looking at the changes in the price of chemical products in the past, the price of 1-bromo-4-methoxyisoquinoline varies from tens to hundreds of yuan per gram. However, this is only an approximate number, and the actual price depends on the supply and demand of the market and the situation of production. In order to know the exact price, it is necessary to consult the chemical raw material supplier in detail, based on their quotation, in order to obtain the current exact price range.
