Quality Control

Our Castalin is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including HPLC, NMR, and mass spectrometry. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request for 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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat and incompatible materials.
