Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We provide comprehensive analytical data to support your R&D and scale-up processes. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request for every batch, ensuring full traceability and quality assurance.

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, sparks, and open flame.
