In the fragrance industry, 2-methylcinnamic acid is also wonderfully useful. It can endow fragrances with a special aroma, making the fragrance more rich and unique. Fragrances are often used by perfumers to prepare unique fragrances, which are used in daily chemicals, such as perfumes, aromatherapy, etc., to increase the layering and attractiveness of their aroma and delight users.
Furthermore, in the field of organic synthesis, 2-methyl cinnamic acid is an important intermediate. With its double bonds and carboxyl groups and other active groups, it can participate in many organic reactions, such as esterification, addition and other reactions. With clever design and operation, a series of high-value-added organic compounds can be synthesized, expanding the boundaries of organic synthesis, providing a variety of raw material choices for materials science and other fields, and promoting the development of related industries.

2-Methyl cinnamic acid is an organic compound. Its physical properties are quite important and are used in many fields such as chemical industry and medicine. The details are as follows:
1. ** Appearance properties **: This substance is often in the state of white to light yellow crystalline powder. Viewed, its powder is delicate and pure in color. This appearance characteristic is convenient for identification and processing in different scenarios.
2. ** Melting point **: The melting point is about 193-195 ° C. As an important physical constant of a substance, the melting point is of great significance for determining its purity and controlling its state under specific temperature conditions. When heated to this temperature range, 2-methyl cinnamic acid melts from a solid state to a liquid state. This property is widely used in material processing, separation and purification.
3. ** Boiling point **: The boiling point is about 300.2 ° C. Knowing the boiling point can help to understand its changes under high temperature conditions. In chemical operations such as distillation and rectification, the boiling point is a key parameter, which is conducive to the effective separation and purification of substances.
4. ** Solubility **: Slightly soluble in water, but soluble in organic solvents such as ethanol, ether, and chloroform. This solubility characteristic makes it suitable for different applications in different solvent systems. In organic synthesis reactions, by virtue of its solubility in organic solvents, a suitable solvent can be selected as the reaction medium to promote the smooth progress of the reaction.
5. ** Odor **: with a weak special odor. Odor, as one of the sensory properties of substances, does not directly determine its chemical properties and applications, but in some products with strict requirements for odor, such as fragrances, food additives, etc., odor characteristics need to be taken into account.

2-Methylcinnamic acid, which is a crystalline powder with a white to yellowish color. This substance has specific chemical properties.
In terms of solubility, 2-methylcinnamic acid is slightly soluble in water, but soluble in organic solvents such as ethanol and ether. This property is derived from its molecular structure, which contains groups such as benzene ring and carboxyl group. The hydrophobicity of the benzene ring interacts with a certain hydrophilicity of the carboxyl group, causing it to behave differently in different solvents.
In terms of chemical activity, the carboxyl group gives it acidity and can neutralize with the base to form the corresponding carboxylate. For example, by reacting with sodium hydroxide, the sodium salt of 2-methylcinnamate can be obtained with water.
In addition, the carbon-carbon double bond of 2-methyl cinnamic acid makes it unsaturated and can undergo an addition reaction. If it is combined with hydrogen in a suitable catalyst, the double bond can be hydrogenated and converted into a saturated carboxylic acid derivative. At the same time, the double bond can also participate in the polymerization reaction to form a polymer.
Its benzene ring also has unique chemical properties and can undergo electrophilic substitution reactions, such as halogenation, nitration, sulfonation, etc. Because the substituents on the benzene ring can affect the reaction activity and check point selectivity, the methyl group and carboxyl group in 2-methyl cinnamic acid have an impact on the electron cloud density distribution of the benzene ring, which in turn determines the difficulty and substitution position of the electrophilic substitution reaction. 2-Methylcinnamic acid is rich in chemical properties, which lay the foundation for its wide application in organic synthesis, medicinal chemistry, materials science and other fields.

The preparation method of 2-methyl cinnamic acid is different from that of the past. In the past, the preparation of this substance was often based on specific raw materials and ingenious steps.
At the beginning, a suitable starting material is taken, and this raw material may have a specific structure to facilitate subsequent reactions. Then, in a specific reaction environment, a specific chemical reaction occurs. The reaction environment is very critical, such as temperature, pressure, catalyst use, etc., all need to be carefully controlled. Temperature may need to be maintained within a certain range. If it is too high, the reaction will be too fast and impurities will be easily generated; if it is too low, the reaction will be slow and take a long time.
During the reaction process, a variety of chemical changes may be involved. Or there is a substitution reaction to replace the specific position of the raw material molecule and introduce the desired group. Then there is an addition reaction to gradually transform the molecular structure into a form close to 2-methyl cinnamic acid.
And when preparing, separation and purification are also important links. After the reaction, the product is often mixed with impurities. Suitable separation methods, such as distillation, extraction, crystallization, etc. are required to separate 2-methyl cinnamic acid from the mixture to obtain a pure product.
Today's preparation method may be improved based on the previous method. With the advance of science and technology, new catalysts and new reaction equipment continue to emerge. The new catalyst may improve the efficiency and selectivity of the reaction, make the reaction more accurate to produce 2-methyl cinnamic acid, and reduce the formation of impurities. The new reaction equipment may better control the reaction conditions, making the reaction more stable and efficient.
Preparation of 2-methyl cinnamic acid requires a deep understanding of chemical principles and operation skills in order to achieve ideal results.

The price of 2-methyl cinnamic acid in the market varies depending on the quality of the product, the amount purchased, and the supply and demand of the market, so it is difficult to be sure. The price of its quality may be slightly higher; if purchased in bulk, the price may be reduced.
In the market of chemical raw materials, the price ranges from tens to hundreds of yuan per kilogram. However, in the market of fine chemicals or reagents, the price may be higher due to higher purity requirements.
Vendors sell 2-methyl cinnamic acid with ordinary purity to chemical manufacturers at a price of about 50 to 150 yuan per kilogram. And high-purity products, used in scientific research or special fields, in the reagent market, the price per gram can reach several yuan, and the conversion price per kilogram is several thousand yuan.
also varies from time to time. If there is a blockage in the supply of raw materials, or if there is a large number of people in need, the price will also rise; if there are many products, the supply will exceed the demand, and the price will drop. To know the exact price, when consulting chemical raw material suppliers and reagent suppliers, and carefully observing the dynamics of the market, the price can be close to the actual price.
