Quality Control

Our Tri-T-Butylphosphonium Trifluoromethanesulfonate, 99% Stabiphos T is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure it meets the specified 99% minimum purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your research or production standards.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
