Quality Control

Every batch of tert-Butyl Xphos Au(Mecn)Sbf6 is manufactured and tested under strict quality protocols to ensure consistency and performance for catalytic applications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity, identity, and moisture content. Our quality system is designed to support cGMP and ISO standards for customers in regulated industries.

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 place. This material is hygroscopic (moisture-sensitive) and easily oxidized; prolonged exposure to air and moisture should be avoided to maintain catalytic activity.
