Overview
Caffeic Acid Tetramer is a polyphenolic compound formed by the oligomerization of caffeic acid monomers. It belongs to the hydroxycinnamic acid family and is notable for its potent antioxidant and anti-inflammatory properties. The compound is naturally found in certain plants but is often synthesized for industrial use. Due to its molecular stability and bioactivity, it has garnered attention in pharmaceutical and nutraceutical research. Its ability to scavenge free radicals makes it valuable in formulations aimed at reducing oxidative stress.
Physical and Chemical Properties
The caffeic acid tetramer typically appears as a brownish powder or crystalline solid. It is soluble in polar organic solvents like methanol and ethanol but has limited solubility in water. The compound exhibits high thermal stability under neutral pH conditions. Its molecular structure features multiple phenolic hydroxyl groups, which contribute to its antioxidant capacity. The tetrameric form enhances its bioavailability compared to monomeric caffeic acid, making it more effective in certain applications.
Main Applications
In the pharmaceutical industry, caffeic acid tetramer is used in formulations targeting oxidative stress-related diseases, such as cardiovascular disorders and neurodegenerative conditions. Its anti-inflammatory properties also make it suitable for topical applications in cosmetics. The food industry employs it as a natural preservative due to its ability to inhibit lipid oxidation. Additionally, it is incorporated into dietary supplements for its potential health benefits, including immune support and metabolic regulation.
Safety and Storage
Caffeic acid tetramer is generally considered safe at low concentrations, but prolonged exposure to high doses may cause irritation. Proper handling includes wearing gloves and avoiding inhalation of dust. Storage recommendations include keeping the compound in a tightly sealed container, away from light and moisture, at room temperature. Stability testing is advised for long-term storage to ensure efficacy.
B2B Procurement Guide
When procuring caffeic acid tetramer, prioritize suppliers with certifications like GMP or ISO to ensure quality and consistency. Request certificates of analysis (CoA) to verify purity, typically measured via HPLC. Bulk purchases may offer cost advantages, but ensure the supplier can meet scalability demands. For pharmaceutical applications, conduct preliminary stability and compatibility tests with other formulation ingredients.
