Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Standard quality parameters include identity confirmation by spectroscopic methods (NMR, IR), purity assessment by chromatographic techniques (GC, HPLC), and control of specific impurities. A comprehensive Certificate of Analysis (COA) detailing all test results and specifications is provided with each shipment and is available upon request. We adhere to cGMP principles where applicable to support our clients in regulated markets.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C/59-77°F). Due to its sensitivity to oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term storage. Keep away from heat, sparks, open flames, and incompatible materials.
