Quality Control

Our Rhapontin is produced and tested under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical documentation, including Certificates of Analysis (COA) with detailed HPLC purity data, identity confirmation (IR, UV), and residual solvent analysis. Our quality commitment aligns with standards applicable to pharmaceutical intermediates and high-grade nutraceutical ingredients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, prolonged exposure to light, air, or elevated temperatures should be avoided to maintain stability and potency. For long-term storage, consider an inert atmosphere.
