Quality Control

Every batch of Brettphos Aucl is manufactured and tested under strict quality management protocols to ensure high purity and batch-to-batch consistency. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and other critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C in a dry, cool environment. This material is hygroscopic (moisture-sensitive) and easily oxidized; prolonged exposure to air, moisture, or elevated temperatures should be avoided to maintain stability and catalytic activity.
