4-Methoxy cinnamic acid is one of the organic compounds. Its physical properties are worth exploring, as follows:
Looking at its appearance, under room temperature and pressure, 4-methoxy cinnamic acid is white to light yellow crystalline powder with fine texture. This form is conducive to observation and use, and can be easily handled in many experiments and industrial operations.
When talking about the melting point, it is about 171-174 ° C. The melting point is an important physical characteristic of a substance, by which the purity of the substance can be judged, and it is a key reference index in separation and purification operations. In this temperature range, 4-methoxy cinnamic acid gradually melts from a solid state to a liquid state, resulting in a phase transition.
In terms of solubility, 4-methoxycinnamic acid is slightly soluble in water. Water is a common solvent, and the degree of solubility of this substance in water is limited, reflecting the weak interaction between its molecules and water molecules. However, it is soluble in organic solvents such as ethanol, ether, and acetone. In these organic solvents, by virtue of specific interactions with solvent molecules, such as van der Waals force, hydrogen bonding, etc., it can be uniformly dispersed to form a solution. This solubility characteristic is of great significance for the selection of suitable solvents for reactions or extractions in the fields of chemical synthesis and drug preparation.
The density of 4-methoxy cinnamic acid also has characteristics. Although the specific value varies slightly due to the measurement conditions, its density determines the location in the mixed system and the spatial distribution relationship with other substances. It has a significant impact on the process of material mixing and delamination in chemical production.
In addition, its stability cannot be ignored. Under conventional environmental conditions, 4-methoxy cinnamic acid has certain stability. However, when exposed to high temperature, strong light or specific chemical substances, its chemical structure may change, triggering chemical reactions, resulting in changes in physical properties.
All physical properties are interrelated and jointly affect the application and treatment of 4-methoxy cinnamic acid in various fields, which is crucial for in-depth understanding and rational use of this substance.

What are the Chemical Properties of 4-Methoxycinnamic Acid?

4-Methoxy cinnamic acid, its properties are also quite different from those of ordinary substances. This is an organic compound with special chemical properties.
Looking at its structure, it contains a group of methoxy and cinnamic acid. The presence of methoxy gives it an electronic effect. Because of its electron conductivity, it can affect the electron cloud distribution of the molecule, which in turn affects its chemical activity. The carbon-carbon double bond in this compound is very active and can often participate in the addition reaction. If it is an electrophilic reagent, the π electron cloud on the double bond is vulnerable to attack, resulting in addition, such as addition to hydrogen halide, which can form halogenated derivatives.
Furthermore, its carboxyl group also has characteristics. The carboxyl group is acidic and can neutralize with bases to form corresponding salts. In the esterification reaction, the carboxyl group can be condensed with alcohols to produce ester compounds. This reaction often requires an acid as a catalyst to promote its formation.
4-methoxy cinnamic acid under light, due to the sensitivity of double bonds or photochemical reactions, causes structural changes. And because of its special structure, it is used in medicine, fragrances, sunscreens and other fields. In sunscreens, it can protect the skin from ultraviolet damage by virtue of its absorption properties to ultraviolet rays. This is also a manifestation of the unique chemical properties of 4-methoxy cinnamic acid.

What is the Production Method of 4-Methoxycinnamic Acid?

The common methods for preparing 4-methoxycinnamic acid are as follows.
First, p-methoxybenzaldehyde and malonic acid are used as raw materials, and the reaction is carried out in a pyridine solvent and catalyzed by piperidine. This is the classic Knoevenagel condensation reaction. The process is as follows: first put p-methoxybenzaldehyde and malonic acid in a pyridine solvent in an appropriate proportion, piperidine catalyzes, heat and stir. Piperidine catalyzes the condensation of malonic acid and p-methoxybenzaldehyde, and the malonic acid loses one molecule of carbon dioxide, thereby generating 4-methoxycinnamic acid. The reaction conditions are mild and the yield is considerable. Pyridine and piperidine can better promote the reaction in the reaction system. After the reaction, organic solvents such as pyridine need to be properly handled to meet the requirements of environmental protection.
Second, p-methoxy styrene is used as the raw material and obtained by oxidation. First, a suitable oxidizing agent, such as active manganese dioxide, is used to react with p-methoxy styrene in a suitable solvent, such as dichloromethane. Active manganese dioxide can selectively oxidize the double bond of p-methoxy styrene to generate 4-methoxy cinnamic acid. This method is relatively simple, but the activity of active manganese dioxide has a great impact on the reaction, and the reaction conditions need to be carefully controlled, and the product separation and purification may require complicated operations.
Third, p-methoxyphenylpropionic acid is used as raw material and prepared by decarboxylation reaction. P-methoxyphenylpropionic acid is placed in an appropriate reaction vessel, and a specific catalyst, such as copper salt, is added to carry out decarboxylation reaction at a certain temperature. During this process, p-methoxyphenylpropionic acid molecules lose their carboxyl groups and transform into 4-methoxycinnamic acid. Although the raw materials of this method are relatively easy to obtain, the reaction conditions are relatively harsh, and factors such as temperature control have a significant impact on the formation of the product, which needs to be accurately grasped.

What is the price range of 4-Methoxycinnamic Acid in the market?

The price of 4-methoxycinnamic acid in the market often varies depending on quality, supply and demand, and source.
If it comes to ordinary commercial grades, the price per kilogram is about tens to hundreds of yuan. If it is of high purity, such as for pharmaceutical and fine chemical researchers, due to strict requirements for purity, the preparation method is also complex, and the price is higher, or more than 1,000 yuan per kilogram.
If the supply of this product in the market exceeds the demand, the price may decline; if the demand is too high, especially when the raw materials are scarce or the demand increases sharply, the price will rise. And the origin is different, the cost is different, if one place is rich in raw materials and the process is mature, the price may be cheaper than others.
However, if you want to know the exact price, you can obtain an accurate price by consulting chemical raw material suppliers, traders, or observing the real-time market conditions.
