Quality Control

Our (-)-Epicatechin is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and NMR, and stringent limits for residual solvents and heavy metals. We provide full traceability and Certificates of Analysis (COA) to ensure compliance with relevant standards for research and commercial use. Specifications can be tailored to meet USP, FCC, or in-house pharmaceutical grade requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation. The product is light-sensitive and easily oxidized; prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and potency.
