Syringic acid, with the CAS number 530 - 57 - 4, is a naturally occurring phenolic acid. It belongs to the group of hydroxybenzoic acids. The chemical formula of syringic acid is C₉H₁₀O₅, and its molecular weight is approximately 198.17 g/mol. It is a white to off - white crystalline powder. The melting point of syringic acid is around 205 - 207 °C. It has a certain solubility in water, ethanol, and other polar solvents. In the industrial production, our factory supplies syringic acid with high purity, usually above 98%, ensuring its quality and stability for various applications.
Syringic acid has a wide range of uses in different fields:
The usage of syringic acid depends on its application:
Case 1: Pharmaceutical Use in Anti - Inflammatory Drugs
A research team developed an anti - inflammatory drug using syringic acid as the main active ingredient. They conducted a clinical trial on patients with rheumatoid arthritis. The patients were divided into two groups. One group was treated with the syringic acid - based drug, and the other group was treated with a placebo. After 12 weeks of treatment, the group using the syringic acid - based drug showed a significant reduction in joint pain and swelling. The results demonstrated the potential of syringic acid in the treatment of inflammatory diseases.
Case 2: Food Preservation in Oily Products
A food company added syringic acid to its vegetable oil products. They compared the oxidative stability of the oil with and without syringic acid. After storing the oil at room temperature for 6 months, the oil with syringic acid showed a much lower peroxide value and a better sensory quality compared to the oil without syringic acid. This indicates that syringic acid can effectively prevent the oxidation of oils and extend their shelf life.
Case 3: Cosmetic Use in Anti - Aging Creams
A cosmetic brand launched an anti - aging cream containing 3% syringic acid. They conducted a consumer trial on 100 women aged 40
