Description of a substance
There is now a substance called * E - Cinnamic Acid *. This substance has unique properties, its color may be light, and its state may be solid. In chemical properties, it has a certain stability and can respond to many reagents. Its melting point is suitable, about [specific melting point value]. This property is crucial when identifying and purifying.

Its application is very wide. In the pharmaceutical industry, it is an important raw material for the synthesis of a variety of drugs. Because of its specific pharmacological activity, it can be used as a good medicine for treating diseases or can help with anti-inflammatory and anti-disease effects. In the world of fragrances, with its unique smell, it can add a different flavor to the essence, making the aroma more rich and mellow. In the food industry, it can be used as a preservative to protect the freshness of food and prolong its shelf life.

As for the production method, the common method is chemical synthesis. With [specific raw material 1] and [specific raw material 2] as the starting materials, under specific reaction conditions, such as suitable temperature, pressure and catalyst, this * E - Cinnamic Acid * can be prepared through a series of reaction steps. However, the method of chemical synthesis requires attention to the precise control of the reaction, and strives for high yield and purity. There is also a method of biosynthesis, which uses the metabolic function of microorganisms to convert the substrate into this substance under specific culture conditions. This method has the advantages of environmental protection and mildness, but the technical difficulty is also high, and further research is required to improve it.
