Quality Control

We maintain a strict quality management system to ensure batch-to-batch consistency and high purity. Our products undergo rigorous quality testing, including HPLC, GC, and NMR analysis, to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing purity, identity, and impurity profiles. We can supply material compliant with cGMP and ISO 9001 standards for critical applications.

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 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 flames.
