Cinnamic Acid

Cinnamic acid is an organic compound with the formula C6H5CH=CHCOOH. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. Classified as an unsaturated carboxylic acid, it occurs naturally in a number of plants. It exists as both a cis and a trans isomer, although the latter is more common. Cinnamic acid is a central intermediate in the biosynthesis of myriad natural products include lignolsto lignin and lignocellulose, flavonoids, isoflavonoids, coumarins, aurones, stilbenes, catechin, and phenylpropanoids. Its biosynthesis is performed by action of the enzyme phenylalanine ammonia-lyase (PAL) on phenylalanine. Cinnamic acid is a precursor for the synthesis of a huge number of plant substances, including lignin, tannins, flavonoids, pigments, many of the flavor components of spices, and various alkaloids, such as morphine and colchicine.

Cinnamic acid is a white crystalline compound with the formula C6H5CH=CHCOOH which is slightly soluble in water, and freely soluble in many organic solvents. It exists as trans and cis isomers, but the trans form is the one most often found in nature and is widely used in commerce. Trans-Cinnamic acid is very important because it is widely used in perfume, food, photographic, polymer and pharmaceutical industries. Landmark provides both cis-cinnamic acid(CAS NO. 621-82-9) and trans-cinnamic acid(CAS NO. 140-10-3).

Cinnamic acid is an organic compound with the formula C6H5CH=CHCOOH. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. Classified as an unsaturated carboxylic acid, it occurs naturally in a number of plants. It exists as both a cisand atransisomer, although the latter is more common. Cinnamic acid is a central intermediate in the biosynthesis of myriad natural products include lignolsto lignin and lignocellulose), flavonoids, isoflavonoids, coumarins, aurones, stilbenes, catechin, and phenylpropanoids. Its biosynthesis is performed by action of the enzyme phenylalanine ammonia-lyase (PAL) on phenylalanine. Cinnamic acid is a precursor for the synthesis of a huge number of plant substances, including lignin, tannins, flavonoids, pigments, many of the flavor components of spices, and various alkaloids, such as morphine and colchicine. Usage: Cinnamic acid is an important substance because it is widely used in perfume, food, photographic, polymer and pharmaceutical industries, as well as for clinical and toxicological Studies. Until now, many methods have been reported for its determination, such as titrimetry, differential-pulse polarography,spectrophotometry, mass spectrometry, HPLC, electrokinetic capillary chromatography, capillary electrophoresis, gas chromatography and liquid chromatography. However, there are many disadvantages over these methods, such as long-response time, reagent consumption, complicated operation, etc. 1.flavors and fragrances It can be used as an aromatic mixture in soaps, shampoos, washing powders, and daily cosmetics. Cinnamonic acid is used to prepare apples and cherries, which can be used as apple flavor, cherry flavor, fruit flavor, and floral fragrance. It has the effect of inhibiting the formation of black tyrosinase, has a certain insulating effect on ultraviolet rays, can make brown spots lighter or even disappear, and is one of the essential ingredients in advanced sunscreen. Cinnamic acid itself is a kind of spice, which has a good aroma-retaining effect. It is usually used as a raw material for fragrant, which makes the aroma of the main fragrance more volatile. 2.the pharmaceutical industry In the pharmaceutical industry, it can be used as an important drug for the synthesis and treatment of coronary heart disease. It can be used as a heart-to-heart and heart-to-heart, as well as synthetic chlorpheniric acid and cinnamyl piperazine. It can be used to make "Xin Kean", local anesthetic, fungicide, hemostasis. Medicine, etc. Chlorobenamide and cinnamyl piperazine can also be synthesized for use as a spine bone relaxant and an antispasmodic agent. Mainly used for cerebral thrombosis, cerebral arteriosclerosis, coronary artery cirrhosis and other diseases. It has a significant inhibitory effect on the proliferation of lung adenocarcinoma cells.
