Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We provide material of consistent high purity, supported by comprehensive analytical data. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request for every batch, ensuring full traceability and reliability for your critical R&D and production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep away from heat, sparks, and open flame.
