Chemical Structure

Basic Info
3, 4, 5-trimethoxycinnamic acid is a derivative of cinnamic acid and an important intermediate in organic synthesis, which has very important applications in medicine, food and polymer materials. In drug synthesis, it can be used to synthesize the vasodilator cinpezide. Cinepazide is a widely used calcium channel blocker, which can prevent calcium ions from transmembrane into vascular smooth muscle cells and cause smooth muscle relaxation, relieve vasospasm, reduce vascular resistance, and increase blood flow to the brain and heart.
With the development of science and technology and the continuous expansion of market demand, the application field of 3, 4, 5-trimethoxycinnamic acid continues to extend. Cinnamic acid derivatives containing hydroxyl group can be obtained by one-step hydrolysis, and these derivatives have excellent antioxidant activity, which increases with the increase of the number of phenolic hydroxyl group. At the same time, 3, 4, 5-trimethoxycinnamic acid has a reactive carboxyl active site, easy acyl chlorination, and other functionalization to achieve different functions and applications.

Product Packaging
1. Pharmaceutical industry
3,4,5-Trimethoxycinnamic Acid is an important drug intermediate, mainly used to synthesize the vasodilator Cinepazide Maleate, which can inhibit calcium ion influx, dilate cerebral blood vessels and coronary arteries, improve microcirculation, and is used to treat cardiovascular and cerebrovascular diseases, peripheral vascular diseases, tinnitus and deafness. In addition, its derivatives such as 3,4,5-Trimethoxycinnamic Acid have anticonvulsant activity and can be used to treat epilepsy.
2. Materials Science and Adhesives
3,4,5-Trimethoxycinnamic Acid can be used as a surface treatment agent to improve the adhesion between inorganic fillers (such as quartz, talcum powder, white carbon black) and resins (epoxy, phenolic, polyurethane, etc. It is used to improve the mechanical properties, electrical properties, and moisture resistance of composite material.
3. Skin care and cosmetics
Due to its antioxidant properties, 3,4,5-Trimethoxycinnamic Acid can be used in skin care products to help protect against ultraviolet (UV) damage and environmental pollution, slow skin aging, and may be used as a whitening or anti-inflammatory ingredient.
4.Foods rich in antioxidants
Although it is rarely used directly, its structural analogues such as the hydrolyzed hydroxyls of polyphenols are strong antioxidants. They can be used as a way to prolong the shelf life of food and prevent lipid oxidation.
5. Agriculture and Plant Protection
Some studies have shown that 3,4,5-Trimethoxycinnamic Acid may have the potential to be antibacterial or promote plant stress resistance, and can be used to develop low-toxic pesticides or crop growth regulators, but its current application still needs further research.
