Chemical Properties:

  1. Caffeic acid, scientific name: “3-(3,4-dihydroxyphenyl)-2-propenoic acid.” Molecular formula: C9H8O4; the molecular weight: 180.16. It is presented in plants such as coffee in the form of chlorogenic acid. It is yellow crystals with melting point being 223~225 °C. When it is precipitated in concentrated solution, it contains no crystal water. However, precipitate of crystals from dilute solution contains one molecule of crystallized water. It is slightly soluble in water, and easily soluble in hot water, cold ethanol, and ethyl acetate. Its alkaline solution is orange and exhibits dark green when being mixed with ferric chloride.
    Application: caffeic acid is safe to be applied in cosmetics and has a broader antibacterial and antiviral activity. It can also absorb ultraviolet radiation. A low concentration of it already has inhibitory efficacy on the generation of skin melanin. Its applied amount in the beauty products for whitening is at the range of 0.5 to 2%. It can also be used as additive for the oxidized hair dyes which is good for enhancing the strength of the color.
    Preparation: it can be produced from the Perkin’s reaction between protocatechuic aldehyde and acetic acid,As follows:
    Reaction formula
  2. It is yellow crystals and can be dissolved in water and ethanol.
  3. Light yellow to greenish-yellow powder

Application:

  1.  Reagents for Organic Synthesis.
  2.  Intermediate of caffeic acid; can be used in organic synthesis. 
  3.  Used for Biochemical studies.
  4. antineoplastic, PGE2 synthase inhibitor, PK inhibitor
  5. Caffeic Acid is a constituent of plants, probably occurs in plants only in conjugated forms. Caffeic acid is found in all plants because it is a key intermediate in the biosynthesis of lignin, one of the principal sources of biomass. Caffeic acid is one of the main natural phenols in argan oi.
  6. Caffeic acid can shrink and strengthen microvessels, reduce permeability, improve coagulation function and the number of leukocytes and platelets. Clinically, it is commonly used in the prevention and treatment of various surgical and medical bleeding. It has a significant effect on gynecological bleeding diseases. It is also used for leukopenia caused by chemotherapy, radiotherapy and other reasons, It also has a certain effect on diseases such as primary thrombocytopenia and aplastic leucopenia.
  7. Caffeic acid is widely distributed in a variety of traditional Chinese medicine plants such as Yinchen, artichoke and honeysuckle. It belongs to phenolic acids and has pharmacological effects such as cardiovascular protection, anti mutation and anti-cancer, antibacterial and antiviral, lipid-lowering and hypoglycemic, anti leukemia, immune regulation, cholagogic hemostasis and oxidation resistance. Caffeic acid can shrink and strengthen microvessels, reduce permeability, improve coagulation function, chemicalbook energy and leukocyte platelet count. Clinically, it is commonly used in the prevention and treatment of various surgical and medical bleeding. It has significant curative effect on gynecological bleeding diseases. It is also used for leukocyte thrombocytopenia caused by chemotherapy, radiotherapy and other reasons, It also has a certain effect on diseases such as primary thrombocytopenia and aplastic leucopenia.
  8. Antioxidant natural dietary phenolic compounds found in plants. Inhibit the synthesis of leukotrienes involved in immune regulation, inflammation and allergy. It can also inhibit Cu2 + induced LDL oxidation.
  9. It is a natural phenolic acid compound existing in plants. It is an antioxidant. It inhibits the synthesis of leukotrienes (leukotrienes involve the regulation of immunity, inflammation and sensitivity) and the oxidation of LDL induced by Cu2 +.
  10. Biochemical research
  11. Intermediate of caffeic acid. For organic synthesis
  12. Used as organic synthesis reagent
