Description

(E)-3-(3,5-Dihydroxyphenyl)Acrylic Acid is a specialized phenolic acid derivative with a conjugated acrylic acid moiety, serving as a key synthetic intermediate and a building block for advanced materials. Its molecular structure, featuring two phenolic hydroxyl groups, makes it valuable for applications requiring antioxidant properties, metal chelation, or as a precursor for more complex polyphenolic compounds. This high-purity chemical is essential for researchers and manufacturers in the pharmaceutical, cosmetic, and fine chemical industries.

Application

• Pharmaceutical Intermediate: A crucial building block for synthesizing novel drug candidates, particularly those targeting oxidative stress-related pathways.
• Antioxidant Research: Used in the study and development of natural and synthetic antioxidants due to its polyphenolic structure.
• Cosmetic Actives: Serves as a precursor for formulating active ingredients in skincare products aimed at anti-aging and UV protection.
• Polymer & Material Science: Acts as a monomer or cross-linking agent for creating functional polymers with specific chemical or UV-absorbing properties.
• Fine Chemical Synthesis: Employed in the multi-step synthesis of complex organic molecules, including flavonoids and stilbenes.
• Analytical Reference Standard: Used as a high-purity standard in HPLC and LC-MS for quality control and research in related fields.

Quality Control

Our (E)-3-(3,5-Dihydroxyphenyl)Acrylic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to handle the material under an inert atmosphere for long-term storage and to minimize exposure to air and moisture.
