Quality Control

Our Catacxium(R) Fbu is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high catalytic performance. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and moisture content. We adhere to cGMP standards where applicable, ensuring the material meets the rigorous demands of pharmaceutical and advanced chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and prevent degradation. Keep the container tightly sealed when not in use.
