Description

p-Coumaric Acid Sulfate Disodium Salt is a chemically modified derivative of the naturally occurring phenolic acid, p-coumaric acid, designed for enhanced solubility and stability in aqueous systems. This water-soluble salt form is critical for applications requiring precise delivery of the p-coumaric acid moiety in biological and chemical research. It serves as a valuable intermediate and reference standard for the pharmaceutical, nutraceutical, and cosmetic industries, where its antioxidant and UV-absorbing properties are of significant interest.

Application

• Pharmaceutical Research: Used as a reference standard, biochemical precursor, or active pharmaceutical ingredient (API) intermediate in the development of anti-inflammatory and antioxidant therapies.
• Nutraceutical & Cosmetic Formulations: Incorporated as a stable, bioavailable source of p-coumaric acid in dietary supplements and skincare products for its antioxidant and potential skin-protective benefits.
• Biochemical Studies: Serves as a substrate or inhibitor in enzymatic assays and metabolic pathway research related to phenolic acid metabolism.
• Chemical Synthesis: Acts as a key building block or protected intermediate in the organic synthesis of more complex molecules, including flavonoids and other polyphenolic compounds.
• Analytical Reference: Employed as a high-purity calibrant in HPLC, LC-MS, and other analytical methods for the quantification of phenolic compounds in various matrices.

Quality Control

Our p-Coumaric Acid Sulfate Disodium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, identity confirmation by IR and NMR spectroscopy, and tests for residual solvents and heavy metals to ensure it meets high-purity standards suitable for research and development. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee traceability and consistency.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed in a dry environment to prevent absorption of moisture.
