Volatility is also one of the significant physical properties of this substance. At room temperature and pressure, 2-%E6%B0%9F-4-%E7%94%B2%E6%B0%A7%E5%9F%BA%E5%90%A1%E5%95%B6 (9CI) has a certain degree of volatility. Placed in an open container, its mass can be observed to gradually decrease over time. It has a unique odor in the air. Although it is not pungent or unpleasant, it is also recognizable, which indicates that its molecules have a strong ability to break free from liquid bondage and enter the gas phase. In terms of boiling point, 2-%E6%B0%9F-4-%E7%94%B2%E6%B0%A7%E5%9F%BA%E5%90%A1%E5%95%B6 (9CI) boiling point is in a specific range. When heated under a specific pressure and reaches a certain temperature, the liquid is rapidly converted into a gas, and a large number of bubbles escape from the liquid. This temperature is the boiling point. The specific boiling point reflects the strength and characteristics of intermolecular forces.

2-Hydroxy-4-methoxybenzaldehyde (9CI), this substance has a wide range of uses. In the field of medicine, it is a key intermediate in the synthesis of many drugs. For example, when synthesizing compounds with specific physiological activities, it can act as a starting material. With its unique chemical structure, through a series of chemical reactions, it can build the core structure of drug molecules and help develop various drugs for the treatment of cardiovascular diseases, nervous system diseases, etc.
In the fragrance industry, 2-hydroxy- 4-methoxybenzaldehyde is often used as a fragrance preparation ingredient because of its unique aroma. It can give a different flavor to the fragrance, or add a floral undertone, or create a special atmosphere. It is widely used in perfumes, air fresheners, detergents and other products to improve its aroma quality and uniqueness.
In the field of organic synthesis, it is an important building block for organic synthesis and participates in the construction of complex organic compounds. By virtue of its functional groups, through esterification, condensation, oxidation and other reactions, it is combined with other organic compounds to synthesize materials with special structures and properties, such as for the manufacture of high-performance plastics, coatings, etc., to provide key raw material support for the development of materials science.

To prepare 2-alkyne-4-methoxybenzaldehyde (9CI), there are various methods.
First, it can be obtained by oxidation of the corresponding alcohol compound. If an alcohol containing a specific structure is selected, it can be treated with a suitable oxidant. Common oxidants such as chromium trioxide-pyridine complexes, which can precisely oxidize alcohol hydroxyl groups to aldehyde groups under mild conditions, and have little effect on alkynyl groups and methoxy groups, so as to achieve the purpose of preparing the target product.
Second, halogenated aromatics are used as starting materials. First, the halogenated aromatics are coupled with the alkynylation reagent to construct the alkynyl-aryl structure, and then the methoxy group is introduced. The introduction of methoxy groups can be reacted with suitable methoxylation reagents, such as sodium methoxide, in appropriate solvents and temperatures through nucleophilic substitution reactions. Subsequently, the specific positions on the aromatic ring are formylated. The Vilsmeier-Haack reagent composed of N, N-dimethylformamide and phosphorus oxychloride is commonly used for formylation reagents such as Vilsmeier-Haack reagent, which is composed of N, N-dimethylformamide and phosphorus oxychloride. After this series of reactions, 2-alkynyl-4-methoxybenzaldehyde can be obtained.
Third, starting from compounds with similar structures, it is prepared by functional group transformation. For example, acetophenone compounds containing alkynyl groups and methoxy groups are first prepared, and then the ketone groups are converted into aldehyde groups. The improvement of Huang Minglong's reduction method can be used. Under alkaline conditions, the ketone groups are first reduced to methylene groups with hydrazine hydrate as reducing agent, and then the methylene groups are converted into aldehyde groups through selective oxidation, and finally the preparation of 2-alkynyl-4-methoxybenzaldehyde is realized.

2-% Jing-4-methoxyphenyl (9CI), during storage and transportation, there are several things to pay attention to, which must not be ignored.
First words storage, this substance should be placed in a cool and dry place, away from direct sunlight. Cover the energy of sunlight, or cause it to undergo photochemical reactions, damaging its chemical properties. And it should be well ventilated to prevent the accumulation of harmful gases and affect the quality of the substance. Temperature is also critical and should be controlled within a specific range to avoid changes in the properties of the substance due to high or low temperature. Too high temperature, or cause it to evaporate and decompose; too low temperature, or cause it to solidify and crystallize, are not conducive to its preservation.
As for transportation, make sure to pack it tightly. Packaging materials must be shock-resistant and pressure-resistant to prevent package damage and material leakage due to collisions and bumps during transportation. And the means of transportation should also be clean and free of other chemical residues to avoid chemical reactions with them. During transportation, pay more attention to weather changes. In case of extreme weather such as rainstorm and high temperature, proper protection measures should be taken. In case of rainstorm, prevent the package from being soaked in water; in case of high temperature, when there are cooling measures, keep it at a suitable temperature.
Furthermore, when handling, operators should be cautious, handle it with care, and must not act rashly. And appropriate protective equipment, such as gloves, goggles, etc., is required to avoid direct contact between substances and the human body and damage to human health.
Therefore, when storing and transporting 2% Jing-4-methoxyphenyl (9CI), pay attention to the above to ensure its safety and integrity.
